Explanation / Answer

6) No of mol of phenol = weight/Mwt

        5.5 = (w/94.1)

w = weight of phenol = 518 g

answer: 518 g

7)

No of mol of Li3PO4 = weight/Mwt

                      = 66.6/115.8

           = 0.575 mol

answer: 0.575 mol

8) Na2CO3 ---> 2 Na+   + co3^2-

    1 mol na2CO3 = 1 mol c

no of mol of C = (1.773*10^17/(6.023*10^23)) = 2.94*10^-7 mol

no of mol of Na2CO3 = 2.94*10^-7 mol
