How many moles of HCl are present in a 50mL 3M solution of HCl?
moles = M x L.
To determine how many moles of HCl are present in a 50 mL 3M solution, we need to use the equation:
Molarity (M) = Moles (mol) / Volume (L)
First, convert the volume from milliliters (mL) to liters (L):
50 mL = 50/1000 L = 0.05 L
Now, rearrange the equation to solve for moles:
Moles (mol) = Molarity (M) × Volume (L)
Moles (mol) = 3 M × 0.05 L
Moles (mol) = 0.15 mol
Therefore, there are 0.15 moles of HCl present in a 50 mL 3M solution.
