Calculate the mass of solute present in 50cm³ of 3m sodium hydrogen trioxocarbonate <iv> solution

To calculate the mass of solute present in a solution, we need to know the concentration of the solute in the solution.

In this case, we are given that the solution is a 3m sodium hydrogen trioxocarbonate (IV) solution. The "m" symbol represents the molality, which is the number of moles of solute per kilogram of solvent.

However, we are not given the mass of the solvent used to make the solution, so we can't directly calculate the mass of the solute. To proceed, we need either the mass or the density of the solvent.

Please provide more information to help calculate the mass of the solute.
