4) Calculate the number of moles in 48g of helium.
5) Calculate the Molar Mass of C2H6.​

Answer 1

Explanation:

1. in chemistry mass of a sample of that compound divided by the amount of substance in that sample measured in moles is known as molar mass the unit of molar mass is kg per mole but historically we are measuring in gram per mole
2. in pic
3. in pic
4. 12.046×10^23moles
5. 30g/mol
