(a)
Interpretation:
The determination of the molar mass of a gas at STP if its density is
(a)
Explanation of Solution
The molar mass of a gas at STP can be determined by using the value of its density. The density
The density of the gas is
Substitute the given values in the above expression:
The number of moles of the gas is equal to the ratio of the mass of the gas to the molar mass of that gas.
At STP, the number of moles of a gas is
(b)
Interpretation:
The determination of the molar mass of a gas at STP if its density is
(b)
Explanation of Solution
The density of the gas is
The number of moles of the gas is equal to the ratio of the mass of the gas to the molar mass of that gas.
At STP, the number of moles of the gas is
(c)
Interpretation:
The determination of the molar mass of a gas at STP if its density is
(c)
Explanation of Solution
The density of the gas is
The number of moles of the gas is equal to the ratio of the mass of the gas to the molar mass of that gas.
