Explanation:
Answer:
Mass = 159.8 g
Explanation:
Given data:
Mass of HNO₂ = ?
Moles of nitrous acid = 3.4 mol
Solution:
Formula:
Number of moles = mass / molar mass
We will rearrange this formula.
Mass = number of moles × molar mass
Molar mass of nitrous acid = 47 g/ mol
Mass = 3.4 mol × 47 g/ mol
Mass = 159.8 g
