Question

Calculate the percentage of C,H and O in C10H20O(
menthol)

Answer 1

Answer:

C= 76.92 percent

H= 12.82 percent  

O= 10.26 percent

Explanation:

where C(carbon)= 12. H(hydrogen)= 1 and O(oxygen)=16

C10H20O is (12*10+1*20+16) = 156

for C= 12*10/156 = 120/156*100 = 76.92 percent

for H= 1*20/156*100= 20/156*100= 12.82 percent

for O= 16/156*100= 10.26 percent

Make sure you add them together to get 100 percent
