A volume of 90.0 ml of aqueous koh was titrated against standard solution of h2so4 what is the molarity of the koh solution if 20.7 ml of 1.50 m h2so4 was needed?
Use the formula C1(V1) = C1(V2) to find the unknown concentration. Here, V1 = 20ml and V2 = 33.86ml. Also, C2 is 0.1368M Now plug in these values to find V1 Therefore we have: 20ml(V1) = (0.1368)(33.86) Therefore, V1 = 0.2316M The a 0.2316M solution of H2SO4 was required for the neutralization reaction
Convert g per mole to grams?
first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles
What mass of sucrose should be combined with 472 of water to make a solution with an osmotic pressure of 8.95 at 300?
I hate a little trouble with this one myself until I I figured out why in the hell they gave me density. Here is the work: (minus the units because if you can't figure that out or find it in a book may God save your sorry soul.) To start, find the Molarity: 8.95/(.08206*300)= M now realize a couple things... First, being that Molarity is mol (solute)/Liters (SOLUTION). The solution is the water and the sucrose so you can't just plug in the volume of the water and find moles of the solute. Secondly the give you density for the solution which is the same as the solvent (it doesn't say it in the question but its in the actually question given in the homework and probably why no one has answered this yet). The density of the solvent is 1.00 g/mL (density of water. again, God save your soul if you don't know it or couldn't find it) Now since we know that there are there X moles of sucrose in 1 Liter of solution (the Molarity you got) we find how many grams are there in one liter of solution. Let's say M = .345 then you will take that times the molar mass of sucrose and find the grams per Liter. Once you have this number you can then proceed to take that number from 1000 since the density (here where this bit of info finally comes in) is 1 g/mL, ever Liter of solution is 1 kg of solution. Now you do some basic math and set 2 fractions equal to each other, one being X (grams of sucrose) over your grams of water that gave you in the problem and the other being the the amount of grams you found from your Molarity over the amount of water you found you had in 1kg of solution. And there it is just plug in whatever numbers you got and you will get the answer.
