A learner is given 6.02g magnesium sulfate
calculate the number of moles in magnesium sulfate

Answer 1

0.05 moles

Step-by-step explanation:

Formula: MgSO
`_(4)`

Molecular mass: 120.366 g/mol

Given mass: 6.022 g

Setting up ratio between moles and mass:

moles : mass

1 : 120.366

X : 6.022

X = 6.022/120.366

X = 0.05 moles
