What mass of sodium carbonate must be used to get a 300.0 mL solution with a 2.50 mol/L...

Question:

What mass of sodium carbonate must be used to get a 300.0 mL solution with a 2.50 mol/L concentration? And what volume of water must 60.0 g of potassium hydroxide be added to in order to get a 0.10 mol/L solution?

Molarity

Molarity is one of the concentrations of a solution. Molarity is defined as the number of moles of solute (usually solid phase) dissolved in the number of the solvent (usually water). The equation for molarity is:

{eq}\rm M \, = \, \dfrac{n}{V} {/eq}

which,

M = Molarity, n = moles of solute (mol), V = Litres of solution.
