Question

The mass of 1.12 liters of gas y at stp is found to be 6.23 g. the molar mass of gas y is

Answer 1

To find the molar mass of gas y at STP, divide the given mass of the gas by its volume. The molar mass is equal to 5.55 g/mol.

Step-by-step explanation:

To find the molar mass of gas y, we can use the formula: Molar Mass = Mass / Volume. In this case, the mass is given as 6.23 g and the volume is given as 1.12 liters. Plugging these values into the formula, we get: Molar Mass = 6.23 g / 1.12 L = 5.55 g/L. Therefore, the molar mass of gas y is 5.55 g/mol.

Answer 2

To find the molar mass of gas y, divide the mass of the gas by the number of moles. In this case, the molar mass of gas y is 6.23 g/mol.

Step-by-step explanation:

To find the molar mass of gas y, we need to convert the mass of the gas to moles using the ideal gas law equation PV = nRT. At STP (standard temperature and pressure), the volume of 1.12 liters of gas is equivalent to 1 mole of gas. Therefore, the molar mass of gas y can be calculated by dividing the mass of the gas by the number of moles:

Molar mass = Mass of gas / Number of moles

Since the mass of the gas y is given as 6.23 g and the volume is 1.12 liters, we have:

Molar mass = 6.23 g / 1 mole = 6.23 g/mol

Therefore, the molar mass of gas y is 6.23 g/mol.
