The compound C_(6)H_(12)O_(4) contains

Answer»

22 atoms per mole
TWICE the mass percent of H as compared to the mass percent of C
six times the mass percent of C as compared to the mass percent of H
thrice the mass percent of H as compared to the mass percent of O

Solution :There are `6.022xx10^(23)` entities in 1 mole. Atomic mass of carbon =12 atomic mass of hydrogen =1 |atomic mass of oxygen =16 molecular mass = `(6xx12)+(12xx1)+(4xx16)=71+12+64=148`\ mass percentage of carbon =72/148 =49% mass percentage of hydrogen =12/148 =8% Mass percentage of oxygen =64/148=43%
