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.
