Question
What is the mass of 0.022 mol of H2O?Give your answer in grams and to three decimal places.(Molar mass of H2O = 18.01 g mol-1)
Solution
To find the mass of a certain number of moles of a substance, you can use the formula:
mass = number of moles * molar mass
Here's how:
-
The number of moles given is 0.022 mol.
-
The molar mass of H2O (water) is 18.01 g/mol.
-
Multiply the number of moles by the molar mass: 0.022 mol * 18.01 g/mol = 0.39622 g.
So, the mass of 0.022 mol of H2O is 0.396 g when rounded to three decimal places.
