a a 300 .0 ml portion of h2o is added to 300.0 ml of 0.250 m h2so4.what is the new molarity?​

Respuesta :

Answer:

0.125 M

Explanation:

Initial volume = 300 mL

Final Volume = 300+300 = 600 mL

Initial Molarity = 0.25 M

Since the same amount of water is added to the sulfuric acid the molarity will be halved.

[tex]\dfrac{0.25}{2}=0.125\ \text{M}[/tex]

The above result can be elaborated by the following steps

[tex]\text{Initial molarity}\times\dfrac{\text{Initial volume}}{\text{Final volume}}\\ =0.25\times\dfrac{300}{600}\\ =0.25\times\dfrac{1}{2}\\ =0.125\ \text{M}[/tex]

So, the new Molarity is 0.125 M
