Question

How many moles are in 50 grams of cobalt?

help asapp

Answer 1

hey there!

atomic mass cobalt = 58.9332 amu

therefore:

1 mol Co ------------ 58.9332 g

moles ------------ 50 g

moles = 50 x 1 / 58.9332

moles  = 50 / 58.9332

 = 0.8484 moles of Co

Hope this helps!

Answer 2

0.8484 moles are in 50 grams of cobalt.

What are moles?

A mole is defined as 6.02214076 × $10^{23}$ of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

Atomic mass cobalt = 58.9332 amu

Therefore:

1 mol Co ------------ 58.9332 g

moles ------------ 50 g

moles = 50 x 1 ÷ 58.9332

moles  = 50 ÷ 58.9332

= 0.8484 moles of Co
