Hello!

In a schools laboratory students require 50.0 mL of 2.50 H2SO4 for an experiment but only available stock solution of the acid has a concentration of 18.0m. What volume of the stock would they use to make the required solution  

0.900 mL  

1.11 mL  

6.94 mL  

7.20 mL

We have the following data:

M1 (initial molarity) = 2.50 M (or mol/L)

V1 (initial volume) = 50.0 mL → 0.05 L

M2 (final molarity) = 18.0 M (or mol/L)

V2 (final volume) = ? (in mL)

Let's use the formula of dilution and molarity, so we have:

The volume is approximately 6.94 mL

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
