Question

How many moles of hcl are in 248 ml of 2.2 m hcl (density = 1.03 g/ml)?

Answer 1

To find the number of moles of HCl in 248 mL of 2.2 M HCl solution, use the formula: Moles of solute = Volume of solution (in liters) × Molarity. Convert the given volume of solution to liters, then substitute the volume and molarity values into the formula.

Step-by-step explanation:

To find the number of moles of HCl in 248 mL of 2.2 M HCl solution, we need to use the formula:

Moles of solute = Volume of solution (in liters) × Molarity

First, convert the given volume of solution to liters:

248 mL = 248/1000 = 0.248 L

Then, substitute the volume and molarity values into the formula:

Moles of HCl = 0.248 L × 2.2 M = 0.5456 moles of HCl

Therefore, there are approximately 0.5456 moles of HCl in 248 mL of 2.2 M HCl solution.
