Explanation / Answer
5.
molarity = W/G.M.Wt *volume in L
0.75 = 500/213*volume in L
volume in L = 500/213*0.75 = 3.13L >>>>answer
6. 3Na2S + 2AlPO4 ---------> 2Na3Po4 + Al2S3
E. 3,2,2,1
7. no of moles of CO2 = W/G.M.Wt
= 3.7197*10^3/44
= 84.52 moles
8. no of molecules = no of moles * 6.023*10^23
= 12.3*6.023*10^23
= 7.4*10^24 molecules
E. 7.4*10^24
9. no of moles = W/G.M.Wt
= 387.1/148.314
= 2.609 moles
C.2.609
