A 0.131 M ZnCO3 solution is made from 11.79 g of solute? What is the volume of the solution?

Question

what is the formula for finding volume?????
and also the molar concentration????

Answer 1

Molarity = moles/volume (in litres). Molarity is the same as molar concentration.

So volume = moles/molarity.

Now divide 11.79 by the Mr of ZnCO3 to get the moles of it.

You now have moles and molarity (0.131), so you can calculate the volume.
