Calculate the mass of 3.4 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to de
Zina [86]

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

What is an empirical formula for a compound that is 82.2% nitrogen and 17.8% hydrogen
makkiz [27]
Percent to mass
Mass to mole
Divide by small
Multiply 'til whole

Assume 100 g of substance, then 82.2 g N and 17.8 g H.

82.2 g N * (1 mol/14.01 g N) = 5.86 mol N
17.8 g H * (1 mol/1.01 g H) = 17.6 mol H

Divide by the smallest mole
17.6 H / 17.6  = 1 H
5.86 N / 17.6 =  1/3 N

Multiply to make whole number ( x3 in this case)
3 x 1 H = 3H
3 x 1/3 N = 1 N
