To find how many millilitres of a 16.0 M HNO3solution are needed to dissolve 24.8 g of CuS.
Concept Introduction:The number of moles of substance can be calculated from mass and molar mass as follows:
Also, molarity of solution is number of moles of solute in 1 L of the solution. It is mathematically represented as follows:
Here, n is number of moles of solute and V is volume of solution.
