Question

At STP, 0.44g of a gas has the volume of 224 cm^3. What is the molecular mass of the gas?​

Answer 1

Answer:

44g is the molar mass of gas.

Explanation:

2200 cm^3 of a gas at STP = Molar mass

Hence,

224 cm^3 of gas = 0.44 g

22400 cm^3 of gas = 0.44g / 224 cm^3 )× 22400

= 9856/ 224 = 44 g

hope it will help you

Answer 2

Answer:

44g

Explanation:

22.4l = 22.4×1000 cm^3

= 22400cm^3 [As 22.4l at STP of any gas = molar mass of that gas]

here,

224cm^3 = 0.44g

22400cm^3 = (0.44×22400)/224 g

= 44g

therefore the molecular mass of the gas is 44g.
