What mass does 4.41 moles of cobalt have? Help

260 g

Explanation:

Data obtained from the question include:

Mole of cobalt (Co) = 4.41 moles

Mass of cobalt (Co) =...?

The mole of a substance is related to its mass according to the following equation:

Mole = mass / Molar mass.

With the above formula, we can obtain the mass of 4.41 moles of cobalt as follow:

Mole of cobalt (Co) = 4.41 moles

Molar mass of cobalt = 59 g/mol

Mass of cobalt (Co) =...?

Mole = mass /Molar

4.41 = mass / 59

Cross multiply

Mass of cobalt = 4.41 × 59

Mass of cobalt = 260 g

Therefore, the mass of 4.41 moles of cobalt is 260 g

the answer is b. dilution
