Answer:
Applying mole concept,
1 mole = molecular weight in gram.
Molecular weight of C
12
H
22
O
11
=12×12+22×1+11×16=342
Molecular weight of CO
2
=12+2×16=44
Molecular weight of CaCO
3
=40+12+3×16=100
Molecular weight of H
2
O=16+2×1=18
The results can be calculated as:
Weight of a sample in gram = number of moles × molar mass
(a) 0.2 moles of C
12
H
22
O
11
=0.2×342=68.4 gm
(b) 2 moles of CO
2
=2×44=88 gm
(c) 2 moles of CaCO
3
=2×100=200 gm
(d) 10 moles of H
2
O=10×18=180 gm
Hence, 2 moles of CaCO
3
weighs more than other compounds.
