Answer: The mass of nitrogen dioxide for given number of moles are 158.7 grams.

Step-by-step explanation:

To calculate the mass for given number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Moles of nitrogen dioxide = 3.45 moles

Molar mass of nitrogen dioxide =
[14+(2* 16)]=46g/mol

Putting values in above equation, we get:

$3.45mol=\frac{\text{Mass of }NO_2}{46g/mol}\\\\\text{Mass of }NO_2=(3.45mol* 46g/mol)=158.7g$

Hence, the mass of nitrogen dioxide for given number of moles are 158.7 grams.
