Question

Hoqw many molecules are in 5.23 g of glucose

Answer 1

Answer:

180 g glucose has = N molecules

5.23 g glucose has

= 5.23 x 6.023 x 1023/180

= 1.75 x 10^22

Answer 2

Answer:

molecular weight of glucose 180.156 so no of molecules of glucose = 0.02903

No of molecules in one mole = 6.022×10 raise to the power 23

so the no of glucose molecules in 5.23g will be = 6.022×10^23×5.23/180.156

for which the answer is 1.748×10^22 molecules.
