How many moles of acetaminophen are in a 0.8mL (0.0008L) dose of infants Tylenol

Answers

Answer:

0.007 mol

Explanation:

Step 1: Given data

Volume of acetaminophen: 0.8 mL

Step 2: Calculate the mass corresponding to 0.8 mL of acetaminophen

The density of acetaminophen is 1.26 g/mL.

0.8 mL × (1.26 g/mL) = 1 g

Step 3: Calculate the number of moles corresponding to 1 g of acetaminophen

The molar mass of acetaminophen is 151.16 g/mol.

1 g × (1 mol/151.16 g) = 0.007 mol

A train travels 846 miles in 9 hours. What is the average speed of the train?

Answers

Answer:

The answer is 94 miles an hour.

Explanation:

Speed equals distance divided by the time taken to cover that distance. So to find the average speed of the train just divide the distance covered (846 miles) by the time taken by the train to cover that distance (9 hours) and that equals 846/9 equals 94 miles in one hour.

Which statement is true about a rock layer deposited on top of another rock layer?
A- It is younger than the rock layer below.
B- It is older than the rock layer below.
C- It is the same age as the rock layer below.
D- It is no different than the rock layer below

Answers

Hello there!

Your answer is C.

Answer:

The right option is; A. It is younger than the rock layer below.

Explanation:

A rock layer deposited on top of another rock layer is younger than the rock layer below. This is based on the law of superposition which states that in any undeformed sequence of rocks that are laid down in layers, the youngest layer of rock will be on top of the sequence, while the oldest layer will be at the bottom of the sequence.

If a sealed 3.0L container has a pressure of 1.0 atm at 20.0 C and is heated to a temperature of 450. K. What is the pressure inside of the container at this temperature?

Answers

The pressure : 1.536 atm

Further explanation

Same container=same volume⇒the volume is constant

Gay Lussac's Law

When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature

[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

P₁=1 atm

T₁=20+273=293 K

T₂=450 K

the pressure :

[tex]\tt P_2=\dfrac{P_1.T_2}{T_1}\\\\P_2=\dfrac{1\times 450}{293}=\boxed{\bold{1.536~atm}}[/tex]

Answers

Answer:

700 mL of ethanol would be added

Explanation:

Given data:

Volume of ethanol added to make 40% v/v solution = ?

Total volume of solution = 1750 mL

Solution:

We will calculate the 40% 1750 mL which will be the volume of ethanol added to the water to make 40%v/v solution.

(40/100)× 1750 mL

0.4 × 1750 mL

700 mL

700 mL of ethanol would be added.

In each case, state whether the forces are balanced or unbalanced. If unbalanced, calculate the net force and describe the direction of the resultant force.

Answers

Answer:

Check explanation section.

Explanation:

In order to understand balanced force and unbalanced forces the first law of Newton should be considered as a basic knowledge.

For Balanced forces, there is equal equality in the direction of the forces. In balanced forces, there is no acceleration.

For unbalanced forces, there is acceleration that is go say there is going to be movement. Therefore, net force is equal to unbalanced forces.

(i) Suitcase dropped from a height.

Answer: since there is movement that is acceleration, then the force here is unbalanced force. The resultant force is downwards.towards the greater force direction.

(ii) A bicycle moving with constant velocity on a straight road.

Answer: As the bicycle moves at constant velocity on the straight road the force here is Balanced. Frictional forces balances the forces from the cyclist.

PLEASE READ THIS ITS ATACTHMENT TO PART 1Part 2Buck : Dazed, suffering intolerable pain from throat and tongue, with the life half throttled out of him, Buck attempted to face his tormentors.But he was thrown down and choked repeatedly, till they succeeded in filing the heavy brass collar from off his neck. Then the rope was removed, and he was flung into a cagelike crate. here he lay for the remainder of the weary night, nursing his wrath and wounded pride. Buck: And each time the joyful bark that trembled in Bucks throat was twisted into a savage growl. But the saloon-keeper let him alone and he could not understand what it all meant. What did they want with him, these strange men? Why were they keeping him pent up in this narrow crate? He did not know why, but he felt oppressed by the vague sense of impending calamity and in the morning four men entered and picked up the crate. Whereupon he lay down sullenly and allowed the crate to be lifted into a wagon. Then he, and the crate in which he was imprisoned, began a passage through many hands. Clerks in the express office took charge of him; he was carted about in another wagon; a truck carried him, with an assortment of boxes and parcels, upon a ferry steamer; he was trucked off the steamer into a great railway depot, and finally he was deposited in an express car. For two days and nights this express car was dragged along at the tail of shrieking locomotives; and for two days and nights Buck neither ate nor drank. In his anger he had met the first advances of the express messengers with growls, and they had retaliated by teasing him. He flung himself against the bars, quivering and frothing. He did not mind the hunger so much, but the lack of water caused him severe suffering and fanned his wrath to fever pitch. Buck:That had given them an unfair advantage; but now that it was off, he would show them. They would never get another rope around his neck. His eyes turned bloodshot, and he was metamorphosed into a raging fiend. Four men gingerly carried the crate from the wagon into a small, high-walled backyard. A stout man, with a red sweater that sagged generously at the neck, came out and signed the book for the driver. That was the man, Buck divined, the next tormentor, and he hurled himself savagely against the bars.
