What is the molar mass of a gas if 0.281 g of the gas occupies a volume of 125 ml at a temperature 126 °c and a pressure of 777 torr?

The molar mass of gas is 72.03 g/mol.

Explanation:

Volume of the gas = V = 125 mL= 0.125 L

Pressure of the gas = P = 777 torr = 1.021 atm

(1 torr = 0.0013 atm)

Temperature of the gas = T= 126 °C = 399 K

Mass of the gas = 0.281 g

Number of moles of gas = n =

Using Ideal gas equation:

M = 72.03 g/mol

The molar mass of gas is 72.03 g/mol.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
