How much sugar (C12H22O11) will be required if each person
on the earth is given 100 molecules of sugar? The population
of the earth is 3 x 10^10
(Ans. 170.43 x 10^11g]
​

Answer 1

Answer:

170.43 x 10^-11g

Explanation:

By Mole Concept

1) C12H22011= (12x12)+(1x22)+(16x11) amu

= 342 amu

2) Hence; 1 mole of sugar = 342 grams

3) Weight Of {(6.022... x 10^23)/(6.022...x 10^21)} molecules= 342g/6.022... x 10^21

4) = Weight of 100 molecules = 342g/6.022...x10^21

5) Hence; 3x10^10 x 100 = (342 x 3x10^10)/6.022... x 10^21

6) = 56..... x 3x10^-11

7) = 170.43 x 10^-11 grams

*Hence your given answer is wrong

I ask you to confirm with your teacher
