Question

find the ratio of the number of water molecules in one tablespoon of water to the number of tablespoons of water on the entire earth.

FIND THE RATIO OF THE NUMBER OF WATER MOLECULES IN ONE TABLESPOON OF WATER TO THE NUMBER OF TABLESPOONS OF WATER ON THE ENTIRE EARTH.

Answer 1

The solution for this question is given below

1 tablespoon water = 15 grams. Total volume of water on earth = 1.386 x 10 km² - 1.386 x 109 x 1012 litres So, total mass of water on earth = 1.386x102 kg = 1.386 X 10249 Number of water molecules in t tablespoon water. - Given mass & Avogadro's Number Mass of Imole = 15 x 6.022X1023 18 = 5.018 X 1023 Now, number of tablespoons of water on entire earth. = Total mass of water on earth. Mass of 1 tablespoon water = 1.386 X 1024 = 9.24 x 1022 15 Therefore, the required ratio is , No. of water molecules. 5.018 X1023 No of tablespoon 9.24 x 1022 NW = 5.43 NT
