Which of the following solutions contains the largest total concentration of ions, assuming complete dissociation

.010 m aluminum chloride
.010m sodium chloride
.010m aluminum sulfate
.010m calcium chloride

In their chemical formulas, aluminum chloride is AlCl₃, sodium chloride is NaCl, aluminum sulfate is Al₂(SO₄)₃, and calcium chloride is CaCl₂. These are all ionic compounds, so they completely dissociate when solvated and conduct electricity as electrolytes. The largest concentration would be 0.010 M aluminum sulfate because it produces 5 ions when dissociated: 2 ions of Al³⁺ and 3 ions of SO₄²⁻. Thus, it's concentration would be 5 times larger: 5(0.01) = 0.050 M.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
