How much sugar will be required if each person on the earth is given 100 molecules of sugar? The population of the earth is 3×1010. |

Answer» The sugar given to the entire population on earth is 3 × 1010 × 102 = 3 ×1012 molecules. One mole (6 ×1023) molecules of sugar corresponds to 342 g. Hence, 3×1012 molecules of sugar corresponds to \(\frac{3 \times 10^{12}}{6 \times 10^{23}} \times 342\) = 170.43 x 10-11 g. Therefore, sugar required is 170.43 × 10−11 g. |
