Question

If given of glocose is 45 gm then calculate.

(a) No. of moles
(b) No. of molecules​

Answer 1

Answer:

Glucose molecular formula is C6H12O6

Explanation:

MOLECULAR MASS IS 6*12+12*1+6*16=72+12+96=180gm

34gmof glucose is 45/180=0.25 MOLES.

1. MOLECULES

• 1 MOLE ANY SUBSTANCE CONTAINS 6.O23*10TO THE POWER OF 23 MOLECULES
• 1MOLE OF GLUCOSE - 6.023*10 ^ 23
• 0.25 MOLES - X
• X=6.023*10^23*0.25=1.50574 molecules
