Question

Calculate the mass of 5.8 moles of nitric acid (HNO3). Explain the process or show your work by including all values used to determine the answer.

Answer 1

Molar mass of 365.516

Step-by-step explanation:

To calculate the mass of 5.8 moles of nitric acid or HNO3, is by adding Hydrogen 1.01, Nitrogen 14.01, and Oxygen 16.00,

together and multiplying that by 3.

1.01+14.01+16.00(3)= 63.02 Grams per mole

We multiply 63.02 × 5.8 moles, and we get the mass of 365.516

Answer 2

Mass = 365.45 g

Step-by-step explanation:

Given data:

Mass of HNO₃ = ?

Number of moles of HNO₃ = 5.8 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HNO₃ is 63.01 g/mol

By putting values in the formula,

Mass = 5.8 mol × 63.01 g/mol

Mass = 365.45 g

5.8 moles of HNO₃ have 365.45 gram mass.
