What is the mass (in grams) of a CO_2 gas sample that occupies 5.46 L at STP?

10.7g of

Explanation:

Any gas at STP occupies 22.4 L/mol.

As such:

5.46/22.4 = 0.244 mol of

mass = mol * molecular weight = 0.244 * 44 = 10.7g of

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
