What is the mass of 2.64 moles of water

Given:

Moles of water : 2.64 mol

Mass of 1 mole of water = 18 g/mol

Mole is the measurement of particles an element contain which is the same with Avogadro's number denoted as

 6.02 x 10^23 

Examples: The number of particles found in 18.00 grams of water is equal to 1 mol, which is 6.02 x 10^23 atoms.

In order to get the mass of water, we simply add the mass of 2 mol of Hydrogen, and 1 mol of Oxygen, since water contain  2 moles of hydrogen and 1 mole of oxygen.

1 mole of hydrogen = 1 gram

2 moles of hydrogen = 2 grams

1 mole of oxygen = 16 grams

Molar Mass of Water = Mass of Oxygen + (2) Mass of Hydrogen

Molar Mass of Water = 16 grams  + 2 grams

Molar Mass of Water = 18 grams

Solution:

Multiply the given moles of water to the mass of  1 mole of water.

= (2.64 mol)(18 g/mol)

Noticed that the unit mol cancels, leaving behind gram.

= 47.52 g

2.64 moles of water is equal to 47.52 grams
