- Question #1565c - Socratic
The molarity of the silver nitrate solution is 0 394 mM The balanced chemical equation for this double replacement reaction looks like this AgN O3(aq) +KCl(aq) → AgCl(s) +KN O3(aq) Notice that you have a 1:1 mole ratio between silver nitrate and potassium chloride, which means that you need 1 mole of silver nitrate for every 1 mole of potassium chloride in order for the reaction to take
- Question #c79f3 - Socratic
As you know, molarity is a measure of the number of moles of solute, which in your case would be phosphoric acid, present in
- Determine the formula of A. Molarity B. Molality C. Mole . . . - Socratic
Well, "molarity" is simply the quotient "molarity"="moles of solute" "volume of solution" And "molality"="moles of solute" "kilograms of solvent" For most, dilute, AQUEOUS solutions, "molality"-="molarity" And "mole fraction" is given by the quotient chi_"the mole fraction"="Moles of component" "Total moles present in the mixture solution" And "normality" is a bit of an old-fashioned
- Question #9d6d5 - Socratic
Since molarity is defined as number of moles of solute per liter of solution, decreasing the volume of the solution while keeping the number of moles of solute constant will increase the solution's concentration That happens because you have the same number of moles of solute in a smaller volume of solution
- What is the mass in grams of CaCl_2 in a 3 M CaCl_2 . . . - Socratic
Molarity = mol solute liter of solution A 3 M solution of calcium chloride contains 3 moles of the solute CaCl2 in one liter of solution To convert 3 mol CaCl2 to mass in grams, multiply the given moles by the molar mass: 110 978 g mol 3mol CaCl2 × 110 978g CaCl2 1mol CaCl2 = 300 g CaCl2 (rounded to one significant figure due to 3 mol)
- Question #03339 - Socratic
b) Molarity "Molarity" = "moles of solute" "litres of solution" The volume of a liquid changes with temperature, so molarity is affected by temperature c) Normality "Normality" = "equivalents of solute" "litres of solution" Normality depends on the volume of solution, so normality is affected by temperature
- Question #a14ed - Socratic
Since molarity is defined as the number of moles of solute per liter of solution, increasing the volume while keeping the number of moles of solute constant will result in a decrease in concentration
- Question #9c19a - Socratic
Every time you're looking for a solution's molarity, you must determine how many moles of solute you get in one liter of solution That is what molarity essentially tells you - how many moles of solute you'd get if you had exactly one liter of solution
