Question

Calculate the masses of the following:

(i). 0.1 moles of water (ii). 3 moles of chlorine molecule.​

Answer 1

Answer:

(i)mass of water=1.8gm

(ii)105g=mass of chlorine

Explanation:

no. of my moles=mass of water/molar mass

(i) 0.1=m/18

0.1x18=m

1/10x18=m

1.8g=m

(ii)3= mass of chlorine/molar mass

3x35=mass of chlorine

105g=mass of chlorine
