Question

Mass of 0.5 gram molecule of sugar

Answer 1

The chemical formula of sugar is C12H22O11
1mole = 1gram molecule = molar mass of sugar= 12×12 + 22×1 + 11×16=144 + 22 + 176 = 342g

So 0.5gram molecule of sugar = 0.5 moles of sugar = 0.5 × 342 =171g

HOPE IT HELPS..... :-)

Answer 2

Answer:

12×6+1×22+16×11

72+22+176=270u

mass of 0.5g molecule

0.5×270=135
