Question

calculate mass of 0.5 moles of sugar

Answer 1

mass of C = 12u mass of H = 1u mass of O = 16u

amu of sugar =( 12*12) + (1*22)+ (16*11)

=144 + 22 + 176 = 342u

molar mass = 342 gram

mass = no. of moles * molar mass = 0.5 * 342 = 171 gram

Answer 2

Hi there,

Molar mass of C12H22O11 = (12 × 12) + (22 × 1) + (11 × 16) =342 g.

Since mass of 1 mole of sugar = 342 g of sugar.

Therefore mass of 0.5 mole of sugar = 342 × 0.5 = 171 g.

Hope this help you.
