Question

Calculate no of molecules in 4.4g of co2

Answer 1

44 g of co2 - 1 mole of co2
4.4 g of co2 - 0. 1 mole of co2
1 mole - avagrado no.

Answer 2

molar mass of co2 is 44 grams
so 44 grams of co2 will contain 1 mole of co2
so 4.4g of co2 will contains 0.1 mole of co2
= 6.022*10^-23 by 10
=6.022*10^-24
