WebQuantitative Chemistry 1.1.3. 1.1.3. Concentration and dilution Place the answers to calculations 1 - 9 in order from left to right in the grid below to find which two solutions A - P react together. (1 mark for each correct answer) 1. How many moles of NaCl must be dissolved in 0.5 dm3 of water to make a 4 mol dm 3 solution. 2. WebBoth units are per decimetre cubed, so you just need to convert moles to mass, using the molar mass. Molar mass of H 2 SO 4 = 98 g/mol. Mass of H 2 SO 4 = moles (mol) x molar mass (g/mol) Mass of H 2 SO 4 = 0.1 mol x 98 g/mol = 9.8 g. This is the mass present in 1dm 3 so the concentration = 9.8 g/dm3. coworking space tempe azWebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base. coworking space tampa fl
