What is the mass of 1.75 moles of zinc atoms?

Atomic mass

The atomic mass is the mass of an atom

The S.I unit is in kilogram and they are usually expressed as mass unit

The mass of zinc is 114.415 grams

Solution

Given data

mass of zinc =?

mole of zinc = 1.75

moles Molar mass of zinc = 65.38 g/mol

Mole = reacting mass / molar mass

Cross multiply

mole x molar mass = reacting mass

mass = 1.75 x 65.38

mass = 114.415grams
