Question

Which will form more number of moles than 34g of ammonia?
18g of H2O
132g of CO2
10g of H2
80g of 02​

Answer 1

Answer:

«» 34 g of ammonia (NH3)

Number of moles = Given mass /molar mass

= 34/(14+1*3)

= 34/17

= 2 moles

«» 18 g of H20

Use the same Formula

18 / 1*2 + 16

= 18/18

= 1 mole

«» 132 g of CO2

132/12 + 16*2

132/44

= 3 moles

«» 80g of O2

80/16*2

80/32

= 2.5 moles

132g of CO2 and 80g of O2 both will form more number of moles than 34g of ammonia. 132g of CO2 forms the highest number of moles, i.e.,3 moles.
