Question

5 moles of CO2 has higher mass than 5 miles of H2O?

Answer 1

molar mass of CO2 is 12+2(16)=12+32=44
mass of 1 mole of CO2 is 44
mass of 5 moles of CO2 is 5x44=220
now
molar mass of H2O is 2(1)+16=18
mass of 1 mole of H2O is 18
mass of 5 moles og H2O is 5x18=90
hence from above mass of 5 moles of CO2 is greater than 5 moles of H2O...

hope this helps u:D

Answer 2

mass of CO2 = 44

Molar mass of H2O = 18 g

Mass of 1 mole of CO2 = 44 g

Hence, mass of 5 moles of CO2 = 5×44 = 220

5 moles of H2O = 5×18 = 90 g Hence ,

mass of 5 moles of CO2 is higher than mass

hope its help you
