Question

Calculate the amount of copper (in moles) in a 29.3 g pure copper sheet.

Answer 1

Answer:

1 mole of Copper equals 63.5 g

So, in 29.3 g pure Copper consists of:

(29.3/63.5) moles

= 0.46 moles

I hope this helps.

Answer 2

Answer:

the molar mass of Cu on perodic table =63.546g/mol

moles=grams/molar mass of Cu

=29.3/63.546

=0.46mols of Cu
