The molar mass of NO2 is 46.01 g/mol. How many moles of NO2 are present in 114.95 g? The molar mass of H2O is 18.02 g/mol.

Answer:

2.498 moles of nitrogen dioxide are present in 114.95 grams of nitrogen dioxide.

Explanation:

[tex]n=\frac{m}{M}[/tex]

n = moles of compound

m = mass of the compound

M = molar mass of the compound

We have:

m = mas of the nitrogen dioxide = 114.25 g

M = Molar mas of the nitrogen dioxide gas = 46.01 g/mol

n = ? = Moles of nitrogen dioxide

[tex]n=\frac{m}{M}=\frac{114.25 g}{46.01 g/mol}=2.498 mol[/tex]

2.498 moles of nitrogen dioxide are present in 114.95 grams of nitrogen dioxide.
