Question

What is the molarity of a solution that contains 25 g of hcl in 150 ml of solution? (the molar mass of hcl is 36.46 g/mol.) what should you find first?

Answer 1

Answer: 4.6 M

Step-by-step explanation:

Converting 25 g of HCl to moles, we get 25/36.46 = 0.68568294020845 moles.

Also, 150 mL = 0.150 L

So, the concentration is:

`(0.68568294020845)/(0.150) =\boxed{4.6 \text{ M}}`

Answer 2

Part 1. First, you find the Moles.

Part 2. The correct setup for finding the moles is: 25g HCI x 1mol HCI/36.46g HCI

Part 3. The correct setup to find liters is: 150 mL x 1L/1000mL

Part 4. The molarity of this solution is: 4.6 M HCI
