Question

Determine the number of oxygen molecules in 50.88 g of oxygen if the molar mass of

oxygen molecules is 32.00 g/mol

Answer 1

9.575 x 10^23 molecules oxygen

Step-by-step explanation:

50.88g O x (1 mol O/32.00 g O) x (6.022 x 10^23 molecules O/ 1 mol O)

Cancel out the terms in the bottom to get molecules of O.
