Calculate the amount of solute (in grams) needed to prepare 431.5 g of 8.85% (m/m) LiNO3 solution. A solution is made by diluting 18.2 g glucose (C_6H_{12}O_6) in 0.150 kg water. What is the mass percentage of solute in this solution? The mass of a 14.4% (by...
Step 3: Determine the Molarity of the Solution The third and final step is to plug the values you have obtained in steps one and two into the molarity equation. Plug 0.0117 mol in for m and 0.350 in for V. M = m/V M = 0.0117 mol/0.350 L ...
