In order to make 0.500 L of a 0.475 M solution, you will need to weigh out how many grams of sucrose (MM = 342 g/mol)?
elixir [45]

The first step to solve this problem is to multiply the volume of solution times its concentration to find the number of moles needed, remember that M=mol/L:

0.500L\cdot\frac{0.475mol}{L}=0.2375mol

Now, use the molar mass of sucrose to find the number of grams needed to make the solution. This is, multiply the number of moles needed times the molar mass:

0.2375mol\cdot\frac{342g}{mol}=81.225g

It means that to make 0.500L of a 0.475M you will have to weigh 81.225g of sucrose.
