Question

12.5 mL of 6.0 M KCl is diluted to make a 1.5 L solution. The molarity of the dilution solution is ___ M. (Round atomic masses to the nearest whole number. Include 2 sig figs total in your answer.)

Answer 1

The molarity of the dilution solution is 0.050 M

Further explanation

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

`\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}`

Where

M = Molarity

n = Number of moles of solute

V = Volume of solution

Dilution formula :

`\tt M_1.V_1=M_2.V_2`

M₁=6 M

V₁=12.5 ml

V₂=1.5 L=1500 ml

`\tt 6* 12.5=M_2* 1500\\\\M_2=(6* 12.5)/(1500)=0.05~M\\\\for~sig.fig\rightarrow 0.050~M`
