What is the mass, in grams, of 1.24 mol of water, ##H_2O##?

1.24 mol of water is equal to 22.3 g ##H_2O##

Hi!

Here are the steps on how to find the mass (g) of 1.24 mol water.

Step 1: Determine the Molecular Mass of water using .

2H: 1.00784 X 2 = 2.01568 g

O: 15.9994 g

##"Mol. Mass of " H_2O = 2.01568 g + 15.9994 g = 18.01508 g / "mol H2O"##

Step 2: Multiply 1.24 mol ##H_2O## with the molecular mass.

1.24 mol ##H_2O## x ##18.01508 g / "mol H2O"## = 22.3 g ##H_2O##

note: mol ##H_2O## cancels out.

Hope it helps!
