Question

calculate the mass of 3. 011*10 to the power 24 molecules of water​

Answer 1

Answer:

Pls mark me as brainliest

Explanation:

Mass of 1 mole of water = 2 + 16 = 18

6.023 × 10^24 molecules mass is 18

Then mass of 3.011 × 10^24 molecules = 3.011 × 10^24 × 18 / 6.023 × 10^24 = 9 g approx

Answer 2

1 mole of water is 18 grams as it contains 6.022x 10^23 molecules of water. Therefore by unitary method Na/2 x 10 molecules of water would weight 90grams
