(Solved): a. (1.54\times 10^(-2)(g))+(2.86\times 10^(-1)(g)) c. (8.99\times 10^(-4)(m))\times (3.57\times 10^( ...
a.
(1.54\times 10^(-2)(g))+(2.86\times 10^(-1)(g))c.
(8.99\times 10^(-4)(m))\times (3.57\times 10^(4)(m))b.
(7.023\times 10^(9)(g))-(6.62\times 10^(7)(g))d.
(2.17\times 10^(-3)(g))/(5.022\times 10^(4)(mL))
