Moles of solute per Liter of solution.. M=mol/L What is molality? Moles of solute per Kg of solvent.. m=mol/kg What is mole fraction? Moles of component solving for per total # of moles What is mole percent? Mole fraction X 100 What is mass (or volume) fraction? Mass of solute per total mass of solution What is mass (weight) percent or percent by weight? Mass fraction X 100 What is volume percent or percent by volume? Volume fraction X 100 What us ppm (parts per million)? Mass fraction X 10^6 What is ppb (parts per billion)? Mass fraction X 10^9 What does temperature cause change in? Volume What concentration is temperature dependent? Molarity What do u assume is the solvent if it's not stated in the problem? Water If you are given weight% (mass percent), what sample size will be chosen? 100g of solution If you are given Molarity, what do u assume? 1 Liter (1000 mL) If you are given Molality, what do u assume? 1 Kg (1000g) In problems that are given Molarity & Liters are assumed, the Molarity equals ________ of the solute. The moles To get from grams -> kg, what do u do? Move the decimal 3 places to the left To get from mL -> L, what do u do? Move the decimal 3 places to the left Density = ______/_______ Mass/Volume .remove_background_ad { border: 1px solid #555555; padding: .75em; margin: .75em; background-color: #e7e7e7; } .rmbg_image { max-height: 80px; } Authortessaj21 ID36895 Card SetChem 112 DescriptionReflects how dense the solute is in a solvent Updated2010-09-23T19:36:21Z Show Answers
