Question

Calculate the mass of 1×10^23 molecules of methane

Answer 1

Answer:

Explanation:

1 mole=6.023*10^23 molecules

1 molecule=1/(6.023*10^23) moles

=>1*10^23 molecules=10^23/(6.023*10^23) moles

                                 

 =0.166 moles

=>mass of 1*10^23 molecules of methane=0.166*16    (wt.=no. ofmoles*G.M.W)

  

 =2.656 gm

Answer 2

Answer:

mass of methane is 2.65 gm
