A 65.0 mL aliquot of a 1.60 M solution is diluted to a total volume of 268 mL. A 134 mL portion of that solution is diluted by adding 179 ml of water. What is the final concentration? Assume the volumes are additive. concentration: A 3.94 g sample of a laboratory solution contains 1.26 g of acid. What is the concentration of the solution as a mass percentage? concentration: % acid How many grams of a 19.3% sugar solution contain...
Prepare 150.0 ml of an iodine solution with a concentration of 0.06 g/mL from the bottle of the 0.12 g/mL iodine solution. What is the final volume? Note* 1mole= 100 particles so iodine here= 47moles (The iodine solution is made up of I^2(47moles), OH-(1.00481e-7moles), and H+(1.00481e-7moles). You're adding the iodine solution to 150mL of H20- H+(1.00481e-7moles), and O2(1.00481e-7moles).
