Question

Show that 100g of water and 100g of CO² are not equal in number of mole

Pls explain properly pls

Answer 1

chemical formula of water is H2O
molar Mass of hydrogen(H) is 1u
molar Mass of oxygen (O) is 16
molar Mass of carbon (C) is 12
therefore, molar Mass of CO2 is 12+16(2) = 44 u
and molar Mass of water is 1(2) + 16 = 18u .
we know that no. of mole's = given Mass ÷molar mass
no. of mole's in CO2 = 100÷44 = 2.2 moles
no. of moles in H2O =100÷18= 5.55 moles
hence no. of moles are not equal
