Question

out of 22g of CO2 and 10g of NH3 which has more number of molecule?

Answer 1

Answer: 10g of NH3 has more particles

Explanation

Avagardro's number = is 6.023 x 10^23

Mol wt of CO2 = 22g

Mol wt of NH3 = 17g

No of Moles of CO2 = 22/44 = 0.5 moles = 6.022 x 10^23 x 0.5

                                                                     = 3.011 x 10^23 particles

No of Moles of NH3 = 10/17 = 0.588 moles or almost 0.6 moles

                                              = 6.022 x 10^-23/2  x 0.6 = 3.6132 x 10^23
