Gas X has a density of 2.60/L at STP. Determine the molar of this gas.
Please show me the steps to solve this problem. thanks
You just need the definition.
One mol of a gas at STP occupies 22.4 L.
You have the mass of 1 L. Just calculat the mass of 22.4 L. Piece of cake.

To determine the molar mass of a gas, we can use the equation
molar mass = density × molar volume
where the molar volume of a gas is equal to 22.4 L/mol at STP (Standard Temperature and Pressure).
Given that the density of Gas X is 2.60 g/L at STP, we can calculate the molar mass using the following steps:
Step 1: Convert the density from g/L to g/22.4 L
To do this, multiply the density by the molar volume (22.4 L/mol):
2.60 g/L × 22.4 L/mol = 58.24 g/22.4 L
Step 2: Calculate the molar mass
Since we have determined the mass of 22.4 L of Gas X, this result is equal to the molar mass of Gas X:
Molar mass of Gas X = 58.24 g/22.4 L
Therefore, the molar mass of Gas X is 58.24 g/mol.
