Question

5. Convert into moles:

(a) 6 g of CO2 gas

(b) 20 g of water vapour

(c) 24 g of carbon atoms. ​

Answer 1

Answer:

(a)

no.of.moles = given mass /molar mass

= 6/44

= 0.1 mole

(b) no.of.moles = given mass / molar mass

= 20/18

= 1.1 mole

(c) no.of.moles = given mass / molar mass

= 24 / 12

= 2 moles
