HNO3 = 1+14+3×16 = 48+14+1 = 63

no of moles = given mass/molar mass = 12.6/63 = 1/5

Answer:

The number of moles in 12.6g of nitric acid is equal to 0.2 moles.

Explanation:

Given, the mass of nitric acid = 12.6g

As we know the chemical formula of nitric acid is HNO₃.

Calculate the molecular mass of the nitric acid:-

Molecular mass (HNO₃) = 1 + 14 + 3(16) = 63g/mol

We know that the molecular mass of a compound is the mass of one mole of compound.

So, 63g of nitric acid has moles = 1 mole

12.6g of nitric acid will have moles = $=\frac{12.6}{63}=0.2 \; moles$

Therefore, the number of moles in 12.6g of nitric acid is equal to 0.2 moles.
