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

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
