Question

Mole concept is an important tool for dealing with chemical calculations. The elements have atomic masses while compounds have molecular masses or molar masses. Mole is in fact, a collection of Avogadro’s number (N) of the particles of a substance whether element or compound. The value of Avogadro’s number is 6.022 x 10^23 (a) Find out the mass of 12.044 X 10^23 number of water molecules. *

Answer 2

Answer:

36

Explanation:

No of moles = 12.044 X 10^23  = 2 mole

                        6.022 x 10^23

Molar mass of H2O is 18g

So 18 × 2 = 36

answer is 36
