Question

how many moles of co2 are there in 12.044 *10^23 molecules of co2

Answer 1

one mole of co2=6.022×10^23

=(12.044×10^23)/6.022×10^23
=2 moles

Answer 2

one mole of CO2 = avogethro number
= 6.022*10^23

6.022*10^23 molecule are present in = 1mole
1molecule present in= 1/6.022*10^23
12.044*10^23 molecule present= (1/6.022*10^23) * 12.044*10^23
= 2 mole
