Gas X has a density of 2.60g/L at STP. Determine the molar mass of this gas.

Sorry there was some typos on the previous question.

please show me again steps by steps. thank you =]

Same answer. You just left the g off the density.
One mole of ANY (ideal) gas occupies 22.4 L at STP. You know how much 1 L weighs. Calculate the mass of 22.4 L. (We always assume the gas is ideal unless the problem says it isn't.)

To determine the molar mass of Gas X, you can use the ideal gas law and the known density of the gas at STP.

1. Write down the given information:
- Density of Gas X at STP = 2.60 g/L

2. Recall that the molar mass is the mass of one mole of a substance in grams. To find the molar mass, we need to calculate the mass of 22.4 L of Gas X.

3. Convert the given density from grams per liter to grams per mole:
- Density = mass/volume
- 2.60 g/L = mass/22.4 L
- Solve for mass: mass = 2.60 g/L × 22.4 L = 58.24 g

4. Since we found the mass of 22.4 L of Gas X and want to calculate the molar mass, the mass we found is equal to the molar mass in grams.

Therefore, the molar mass of Gas X is 58.24 g/mol.
