Question

calculate the ratio of moles of 3.6g of water and 4.4g of carbon dioxide. Atomic mass of C = 12u , H = 1u , O = 16u

Answer 1

look the atomic mass of one mole water is 18 gms
and for carbon dioxide it's 44 gm which can be called 1 mole...

by the given data:-
Mole of water= given mass/ Atomic mass
3.6/18
which is equal to 0.2
and for
Carbon dioxide... the same way
mole are equal to 0.1

so ratio is 2:1...
