How does the molecular formula of a compound differ from the empirical formula? Can a compound’s empirical and molecular formulas be the same? Explain.

Answers

Answer 1
Molecular is every element present in the compound eg C2H6, empirical is the smallest whole number ratio of elements in a compound so that would be CH3 as you divide by the highest common factor. Some compounds only have 1 formula if they are simple or have no common factors. Eg methane, CH4 is its molecular and empirical because its the simplest whole number ratio and includes every element in the molecule

How many molecules are there in 5.9 moles of NaCl?

Answers

The number of molecules= 3.55 x 10²⁴

Further explanation

Given

5.9 moles of NaCl

Required

The number of molecules

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

So for 5.9 moles :

= 5.9 x 6.02 x 10²³

= 3.55 x 10²⁴

If you have 40.0 g HCl and 40.0 g NaHCO3, do you have the same number of moles of each?

Answers

They both have a different number of moles

Further explanation

Given

40 g HCl

40 g NaHCO3

Required

moles

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

n = mass : molar mass

So the moles of a compound are affected by its molar mass (inversely proportional)

The larger the molar mass (of the same mass), the smaller the moles

molar mass HCl = 58.5 g/mol

molar mass NaHCO3 = 84 g/mol

mol HCl :

= 40 : 58.5

= 0.684

mol NaHCO# :

= 40 : 84

= 0.476

Answers

There are 5.5 moles of Argon gas in tank

Further explanation

Given

122.6 liters of Argon gas

Required

The number of moles

Solution

Assume at STP

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.

So for 122.6 L :

= 122.6 L : 22.4 L

= 5.47 moles ≈ 5.5 moles

A chip is burned beneath an aluminum container holding 28.7 g of water causing the temperature of the water to increase from 11.3 °C to 33.2 °C. How many joules of heat were absorbed by the water? Water’s specific heat is 4.18 J/gºC

Answers

Answer:

Q = 2627.25 J

Explanation:

Given that,

The mass of water, m = 28.7 g

The temperature of the water to increase from 11.3 °C to 33.2 °C

The specific heat of water is 4.18 J/gºC

The heat absorbed by the water is given by :

[tex]Q=mc\Delta T\\\\Q=28.7 \times 4.18 \times (33.2-11.3)\\\\Q=2627.25\ J[/tex]

So, 2627.25 J of heat is absorbed by the water.
