Question

Find each no of atoms present in 0.5 mole of cane sugar

Answer 1

So, one mole of a substance contains exactly the Avogadro number (N) of particles. Where NS is the number of molecules in the substance. It is given to us that there are 0.5 moles of glucose present. Hence, there are 3.011×1023 molecules in 0.5moles of glucose.

Answer 2

Answer:

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 grams

mass = no. of moles * moles mass = 0.5*

342 = 171 grams
