How many grams are in 0.00321 mol NI

Anika [276]

Solution

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

mol = mass : molar mass

mass = mol x molar mass

Molar mass = 58,6934 g/mol

Input the value :

mass = 0.0321 x 58,6934 g/mol

mass = 1.884 g
