Question

If you start with 55.5 mL of 1.30 M HG and you dilute it due to 188.5 mL what is the new molarity

Answer 1

`\huge\boxed{\sf M_2 \approx 0.38 \ M}`

Step-by-step explanation:

Given data:

Initial volume =
`V_1` = 55.5 mL

Initial Molarity =
`M_1` = 1.3 M

Final volume =
`V_2` = 188.5 mL

Required:

Final Volume =
`V_2` = ?

Formula:

`M_1V_1 = M_2V_2`

Solution:

Put the given data.

Finding new molarity.

`(55.5)(1.3)=(188.5)(M_2)\\\\72.15 = 188.5 (M_2)\\\\Divide \ both \ sides\ by \ 188.5\\\\72.15/188.5 = M_2\\\\M_2 \approx 0.38 \ M\\\\\rule[225]{225}{2}`
