Se tiene un litronde solucion de agua con alcohol con una consentracion del 4.5% v/v ¿Cuanto alcohol se tiene en la solución

Answers

Answer:

45 mL

Explanation:

Tenemos los siguientes datos:

V = 1 L

C = 4,5% v/v

El porcentaje en volumen (%v/v) expresa el volumen de soluto (alcohol en este caso) que hay cada 100 mL de solución. Si la solución tiene una concentración del 4,5% v/v eso quiere decir que hay 4,5 ml de alcohol cada 100 ml de solución, de acuerdo a lo siguiente:

4,5% v/v alcohol = volumen alcohol/ volumen solución x 100 = 4,5 mL alcohol/100 mL solución= 4,5 mL alcohol/0,1 L alcohol

Por lo tanto, al multiplicar por el volumen total de la solución (1 L), obtenemos la cantidad total de alcohol:

4,5 mL alcohol/0,1 L alcohol x 1 L = 45 mL

If 0.583 g of ammonia (NH3) is dissolved to make 250 mL of solution, what is the molarity?

Answers

Answer:

0.137 M NH3

Explanation:

First divide the mass of NH3 by the molar mass of NH3, and then divide by the volume to get molarity.

0.583 g / 17.031 g/mol = 0.0342 mol NH3

0.0342 mol NH3 / 0.250 L = 0.137 M NH3

Based on the data given, the correct rate law of the sample reaction is: C. [tex]R = K[A]^2[B]^1[C]^0[/tex]

What is the rate law?

Rate law can be defined as a chemical equation that is typically used to relate the initial (forward) chemical reaction rate with respect to the concentrations or pressures of the chemical reactants and constant parameters.

Mathematically, the rate law is given by this formula:

[tex]R = K[A]^x[B]^y[C]^z[/tex]

Where:

k is the rate constant.A is the concentration of reactant A.B is the concentration of reactant B.C is the concentration of reactant C.x, y, and z are the order of the reaction.

Based on the data given, the correct rate law of the sample reaction is as follows:

[tex]R = K[A]^2[B]^1[C]^0[/tex]

A balloon is filled with oxygen gas with a volume of 8.70 ML and a temperature of 318.2 K if the temperature increases to 337.8 K what would the new volume be

Answers

Answer:

The new volume will be 9.24 mL.

Explanation:

Charles's law determines that for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

So, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

When studying an initial state 1 and a final state 2, it is satisfied:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

V1= 8.70 mLT1= 318.2 KV2= ?T2= 337.8 K

Replacing:

[tex]\frac{8.70 mL}{318.2 K} =\frac{V2}{337.8 K}[/tex]

Solving:

[tex]V2=337.8K*\frac{8.70 mL}{318.2 K}[/tex]

V2= 9.24 mL

The new volume will be 9.24 mL.

The water is formed from oxygen gas and...hydrogen gas, I'm assuming? It would have been nice for the question to have been a bit more explicit (not blaming you, of course).

Assuming that's the case, our chemical reaction would be:

2H₂(g) + O₂(g) → 2H₂O(l).

We are told that 1 mol of a gas has a volume of 24.0 dm³ at RTP. We can use this relation to determine the number of moles of O₂ gas that reacts given its initial volume, 33.5 dm³.

33.5 dm³ O₂(g)/24.0 dm³/mol = 1.396 mol O₂(g).

Since we are not given any information about H₂(g), or any other reactant for that matter, I am assuming that the O₂(g) is the limiting reactant. According to the equation, the stoichiometric ratio between O₂ and H₂O is 1:2. That is, for every one mole of O₂ that is consumed, two moles of H₂O are formed (i.e., the number of moles of H₂O formed is double the number moles of O₂).

Since 1.396 moles of O₂ reacts, 2(1.396) = 2.792 moles of H₂O are produced. To convert moles of water to grams, we multiply the number of moles of H₂O by the molar mass of H₂O:

(2.792 moles H₂O)(18.015 g/mol) = 50.3 g H₂O.

So, approximately 50.3 grams of water are formed from 33.5 dm³ of oxygen gas at RTP.

convert 555 torr into kpa

Answers

Answer:

73.97 kPa

Explanation:

It's helpful to know the conversion factors and apply them.

First, convert from torr to atm:

555 torr ÷ 760 atm = 0.730 atm

Next, convert from atm to Pa:

0.730 atm × 101,325 Pa = 73967 Pa

Finally, convert to kPa (1000 Pa in 1 kPa):

73967 Pa ÷ 1000 kPa = 73.97 kPa
