Calculate the number of moles of solute in each of the following solutions:

Solution Moles of Solute
4.4 L of 1.00 M CuCl = mol?
3.2 L of 2.60 M K2S= mol?

mols = M x L = ?

mol of solute in 5.00 X 102 mL of 0.250 M HCL.

To calculate the number of moles of solute in each solution, you will need to use the equation:

moles = volume (in liters) * molarity

For the first solution:
4.4 L of 1.00 M CuCl

moles = 4.4 L * 1.00 M
moles = 4.4 mol

So, there are 4.4 moles of CuCl in the first solution.

For the second solution:
3.2 L of 2.60 M K2S

moles = 3.2 L * 2.60 M
moles = 8.32 mol

Thus, there are 8.32 moles of K2S in the second solution.
