Answer:

A. when dissolved in water

Explanation:

Water is an extremely polar molecule, meaning it has a positive end a negative end. When an ionic compound is dissolved, the positive pole of water will be attracted to the negative ion and attach itself to it. The same goes for the positive ions. That's how water breaks down ionic compounds

Answer:

450. g of 0.173 % KCN solution contains 779 mg of KCN.

Explanation:

Mass of the solution = m

Mass of the KCN in solution = 779 mg

Mass by mass percentage of KCN solution = 0.173%

(m/m)\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

0.173\%=\frac{779 mg}{m}\times 100

m=\frac{779 mg}{0.173}\times 100= 450,289 mg

1 mg = 0.001 g

m = 450,289 mg × 0.001 g = 450.289 mg ≈ 450. g

450. g of 0.173 % KCN solution contains 779 mg of KCN.
