| June 25, 2021 | education
The amount of a substance is measured in moles and is denoted by the letter “n”.
To calculate the amount of a substance, given its mass, you must first find the molar mass:
M (HNO3) = 1 + 14 + 16 * 3 = 63 g / mol
We calculate the amount of nitric acid substance according to the formula:
n = m / M = 360 g / 63 g / mol = 5.7 mol.
