When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. pt. 1 A solution is created by dissolving 10.0 grams of ammonium chloride in...

Please clear answer and if you can avoid hand writing. Thanks ahead. An unknown triprotic acid (so “n” = 3) sample of mass 0.225 g required 38.22 mL of 0.09767 M NaOH to neutralize where 2.14 mL of 0.1015 M HCl was used to back titrate, find the molar mass of the unknown solid acid in grams per mole.

A spring stress 0.150 m when a 0.300 kg mass is gently suspended from it as fig below. The spring is then set up horizontally with 0.300 kg mass resting on a frictionless table. The mass is pulled so that the spring is stretched 0.100 m from the equilibrium point, and released from rest. Determine: a) the spring stiffness constant K; b) the amplitude...

moles of 1. You are given 41 0.0 mL of a 1.581 M KC03 solution. There are K present in the solution. (Fomula) CONCENTRATION MOLES VOLUME 2. You are given 83.5 mL of a 2.101 M solution of AgNOs. If all of the water is allowed to evaporate, then the mass of AgNO3 left in the container is g. 3. If 25.0 ml of a...
