What is the mass percent of a solution that contains 45.6 grams ethanol (#C_2H_6O#) in 254 grams of water? How many grams of acetic acid should be dissolved in 100.0 g of water to make a 4.0 percent (by mass) solution of vinegar? of a 60% sugar solution by mixing together a 80% sugar solution and a 50% sugar solution.

What is the molar concentration of #68%# #"nitric acid"#, for which #rho_"acid"=1.41*g*mL^-1#? 22.99/58.44 = 0.3933 Na = 39.33% of NaCl 35,000 worksheets, games, and lesson plans, Spanish-English dictionary, translator, and learning, I need to show work but I do not know how to work this problem out, 36.69 g/100 ml is the solubility of NaCl at 50, To obtain % by mass, you take the mass of NaCl divided by the total mass x100%, mass % NaCl = 36.69 g/135.49 g (x100%) = 27.1% (to 3 significant figures), a Question Quora User. So, #c% = m_(solute)/(m_(solution)) * 100%#, where, #m_(solution) = m_(solvent) + m_(solute)#, There are two ways to change a solution's concentration by mass, Let's take an example to better illustrate this concept.
