Question

How many molecules are contained in .900 mol O2?

Answer 1

(0.900 mol O2) x (6.023 x 10^23 molecules/mol) = 5.42 x 10^23 molecules

Answer 2

There are 5.42 × 10²³ molecules are contained in 0.900 mol O2.

HOW TO CALCULATE NUMBER OF MOLECULES:

• The number of molecules in a substance can be calculated by multiplying the number of moles of the substance by Avogadro's number contained in 0.900 mol O2 as follows:

• no. of molecules = no. of moles × 6.02 × 10²³ molecules

• According to this question, there are 0.900 mol of O2. The number of molecules can be calculated as follows:

• no. of molecules = 0.900mol × 6.02 × 10²³

• no. of molecules = 5.42 × 10²³ molecules

• Therefore, there are 5.42 × 10²³ molecules are contained in 0.900 mol O2.
