Question

What is the mass (in mg) of 2.63 moles of nickel?

Answer 1

Data:
Molar Mass of Nickel = 58,7 g/mol

Solving:
58,7 g → 1 mol
y -------→ 2.63 mol

Solving: (They are proportional measures, the rule of three is made (directly proportional)


`(58.7)/(y) = (1)/(2.63)`
multiply cross

`1*y = 58.7*2.63`

`y = 154.381\:g \stackrel{converting}{\longrightarrow}\:\boxed{y = 154381\:mg}`
