Question
The mass of 11.2 litres of a certain gas at s.t.p. is 24 g. Find the gram molecular mass of the gas
Solution
Given:
Volume of gas at STP = 11.2 litres
Mass of gas at STP = 24 g
Gram molecular mass = ?
The mass of 22.4 L of a gas at STP is equal to its gram molecular mass.
11.2 L of the gas at STP weighs 24 g
Therefore,
22.4 L of the gas will weigh
`24/11.2 xx 22.4 = 48 g`
Gram molecular mass = 48 g
Is there an error in this question or solution?
