Question 112

A marine biologist uses a stock solution of magnesium chloride ( $MgCl2\text{MgCl}_2$ ) to adjust the mineral levels in several experimental coral tanks.

Each tank is treated with 35.0 cm³ of this stock solution. 1.00 dm³ of the stock solution contains 185 g of pure dissolved $MgCl2\text{MgCl}_2$ .

Calculate the total mass of magnesium chloride used to treat 40 experimental tanks.
