Determine the molarity of a solution formed by dissolving 4.00 moles of KBr in enough water to yield 3.00 L of solution.
1 answer:
Molarity (M) is the numer of moles per liter (mol/L)
Both are already given:
mol = 4.00 moles of KBr
L = 3.00 L H2O (water)
Plug them both into the equation:
<u>4.00 mol KBr </u> = 1.33 M KBr (1.33 because of sig figs)<u>
</u>3.00 L H2O <u>
</u>
