Question

determine the mass of 0.5 mole 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.

PLEASE MARK MY ANSWER AS A BRAINLIEST.

Answer 2

hey ..

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

hope it's help u
