Calculate the number of grams of 4.4 % (m/m) NaCl solution that contains 6.20 g of NaCl. Calculate the volume in milliliters of 30 % (m/v) NaF solution that contains 4.3 g of NaF. Calculate the volume in milliliters of 7.0 % (v/v) ethanol solution that contains 10.2 mL of ethanol. Help please! I do not understand what to do with the percents.
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...

A student determines that an aqueous solution that contains 0.196 M potassium fluoride and 0.206 M hydrofluoric acid, also has an H3O+concentration of 8.48×10-4 M. Based on these data, calculate the value of the equilibrium constant K for the equilibrium: HF(aq) + H2O H3O+(aq) + F-(aq) Calculate K as is usually done, omitting the solvent, water, from the expression for K: K = and A student determines that an aqueous solution that contains 0.365 M potassium nitrite and 0.125 M nitrous...
Stuck on how to calculate PPM. Can someone
please explain this to me!
Determine the concentrations of K2SO4, K+, and SO42- in a solution prepared by dissolving 2.36 x 10-4 g K2SO4 in 1.50 L of water. Express all three concentrations in molarity. Additionally, express the concentrations of the ionic species in parts per million (ppm). Note: Determine the formal concentration of SO42-. Ignore any reactions with water. [K, SO4) = 9.03 x10-7 M [K+] = 1.806 x10-6 M [K+]...
