How many grams of copper Cu, 63.54 g/mol are in 3.42 moles copper

Answer 1

Answer:
Mass = 217.30 g

Solution:

Mass and moles are related to each other as,

Moles = Mass / M.mass ---- (1)

Where;
Moles = 3.42

M.Mass = 63.54 g.mol⁻¹

Solving eq. 1 for Mass,

Mass = Moles × M.mass
Putting Values,
Mass = 3.42 mol × 63.54 g.mol⁻¹

Mass = 217.30 g
