Respuesta :

Molar mass of nitric acid (HNO3) =atomic mass of hydrogen + atomic mass of nitrogen +3x atomic mass of oxygen . The molar mass of nitric acid (HNO3) is 63.0144 gram per mole, but you have 3.4 moles. Therefore; the answer is 63.0144 g/mole x 3.4 moles = 214.24896 grams.

The mass of 3.4 moles of nitric acid will be 214.24 gram.

What is mole?

A mole is a unit of chemicals and has the same count of objects.

What is mass ?

The mass of a thing is a measurement of how much matter it holds. The kilogram is the most basic SI unit of mass.

Calculation of molar mass of nitric acid

Molar mass of nitric acid ([tex]HNO_{3}[/tex] ) = mass of H2 + mass of nitrogen + 3 × mass of oxygen.

Molar mass of nitric acid ([tex]HNO_{3}[/tex] ) = 2 + 14 + 48

Molar mass of nitric acid ([tex]HNO_{3}[/tex] ) = 64.g/mole.

Conversion of gram mole.

64 g/mole × 3.4 mole= 217.6 mole.

Therefore, the mass of 3.4 moles of nitric acid 217.6 mole.
