Question

Convert into mole a) 16g of oxygen gas(O2) b)36g of water(H2O) C)22g of carbon dioxide (CO2)​

Answer 1

Explanation:

a) 16g of oxygen

molar mass of O=16g

no. of moles=given mass /molar mass

=16/16=1 mol

b) 36g of H2O

molar mass of H2O=18g

no. of moles=given mass/molar mass

=36/18=2 mol

c) 22g of co2

molar mass of co2=44g

no. of moles=given mass/molar mass

22/44=1/2=0.5 mol
