Answer:

i) 0.05

ii) 0.25

Explanation:

i) given mass = 2.2g

molar mass = 44g

No of moles = given mass/molar mass

                     =  2.2/44

No of moles = 0.05

ii) given mass = 25 g

molar mass = 100g

No of moles = given mass/molar mass

                        = 25/100

No of moles = 0.25 moles
