Emerson Anderson · Answer 1

Answer is: mass of 4,30 moles of sodium is 98800 mg.

n (Na) = 4,30 mol.

m (Na) = ?

m (Na) = n (Na) · M (Na).

m (Na) = 4,30 mol · 23 g/mol.

m (Na) = 98,90 g.

m (Na) = 98,90 g · 1000 mg/1g.

m (Na) = 98900 mg.

n - amount of substance.

m - mass of substance.

M - molar mass of substance.
