How many moles of hcl are in 20 g of hcl
Web2 feb. 2024 · We can do this by multiplying by liters of solution on both sides of the equation. The liters of solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume like so: Moles of solute = (liters of solution) * (Molarity) Moles of solute = (0.50 L) (6.0 M) = 3.0 mol of HCl. Web12 mei 2016 · Explanation: These questions can easily be resolved using the relationship that concentration (or molarity) m = no. of moles / no. of litres. In this case, simply …
