Question

How many milliliters of a 5.0 M H2SO4 stock solution would you need to prepare 105.5 mL of 0.32 M H2SO4?

Answer 1

\(M_1V_1=M_2V_2\)

Answer 2

What is that?

Answer 3

its the eqation used to determine one of the unknowns. U plug in the m and v of one side(which would be ur 105.5 ml of 0.32 M H2so4) and the other side u use the 5.0 M. solve for the last variable

Answer 4

it's the molarity equation \(M=\dfrac{n_{solute}}{L_{solution}}\rightarrow n_{solute}=L_{solution}*M\)

since the moles carried over are constant, system 1 is equal to system 2.

\(L_{solution~1}*M_1=L_{solution~2}*M_2\)

hence: \(M_1V_1=M_2V_2\)
