What is mole?
A mole is described as the quantity of a material that includes precisely 6.02214076 X [tex]10^{23}[/tex] of the substance's elementary constituents.
Given data:
Mole = 5.4
Molar mass = 174.25 g/mol
Mass = ?
Mole can be calculated by using the formula:
Mole = mass / molar mass
Put the value of given data in above equation.
Mass = Mole × molar mass
Mass = 5.4 mole × 174.25 g/mol
Mass = 940.95 gram
Therefore, there are 940.95 gram in [tex]K_{2} SO_{4}[/tex]
