Based on the chemical formula of glucose (C6H12O6), select all the true statements.

a. The mass percent of carbon and oxygen in glucose is the same.

b. In 1 molecule of glucose there are 6 atoms of carbon. T

c. he element with higher mass percent in glucose is hydrogen.

d. In 1 mol of glucose there are 6 mols of carbon.

A) False:

B) True

C) False

D) True

A) The mass of a mol of glucose is 180g,

mass of C in one mol of glucose=6 (12 g) = 72 g

mass of H in one mol of glucose=12 (1 g) = 12 g

mass of O in one mol of glucose=6 (16 g) = 96 g

% mass of C = (72g/180 g) * 100=40%

% mass of O = (96 g/180 g) * 100=53.33%

Therefore the mass percent of carbon and owigen in glucose isn't the same.

b) In 1 molecule of glucose there are 6 atoms of C.

c)

% mass of H = (12 g/180g) * 100=6.67%

Therefore; the element with lower mass percent in glucose is hydrogen.

d) yes, in 1 mol of glucose there are 6 moles of carbon, if the formule was C7H12O6, the numbers of moles would be 7.

A is true

B is true

C is true

D is false?
