Chemistry: Calculating Mass from Moles

What is the mass, in grams, of 1.32 mol of water, H2O ?

Answer: 23.8 g H20

Answer:

The mass of 1.32 mol of water (H₂O) is approximately 23.76 g.

When you have 1.32 mol of water (H₂O), you can calculate the mass in grams using the formula: mass = moles × molar mass. In this case, the molar mass of water (H₂O) is approximately 18.015 g/mol. By multiplying the number of moles (1.32 mol) by the molar mass, you get the mass of 23.76 g.

It's important to understand the concept of molar mass, which is the mass of one mole of a substance. For water (H₂O), you add the atomic masses of hydrogen and oxygen to determine the molar mass. The atomic masses are 1.0079 g/mol for hydrogen and 15.999 g/mol for oxygen.

By utilizing the formula mass = moles × molar mass and substituting the values accordingly, you can calculate the mass of a given number of moles of a substance. In this case, the mass of 1.32 mol of water is approximately 23.76 grams.
