Question

Find the number of molecules in 35.20 g of nitrogen dioxide

Answer 1

find molar mass by dividing grams by molar mass of nitrogen dioxide, then multiple by avogadro’s number to find number of molecules. 4.61 x 10^23 molecules. 3 sf

Answer 2

4.584*10^23 molecules

Step-by-step explanation:

Find molar mass of nitrogen and oxygen on periodic table.

find molar mass of nitrogen dioxide

use this to find moles of nitrogen dioxide

multiply by avagadros number
