A solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of the solid is dissolved in 50.0 g of water, the freezing point of the solution is lowered by 5.26°C. What is the composition by mass of the solid? ----- g NaNO3 ----- g Mg(NO3)2
A solid consists of a mixture of N2NO3 and Mg(NO3)2. When 6.50 g of the solid is dissolved in 50.0 g of water, the freezing point of the solution is lowered by 5.26°C. What the composition by mass of the solid? g NaNO3 g Mg(NO3)2 I think Kf value is 1.86
A sample of CaCl2⋅2H2O/K2C2O4⋅H2O solid salt mixture is dissolved in ~100 mL de-ionized H2O. The oven dried precipitate has a mass of 0.233 g. The limiting reactant in the salt mixture is K2C2O4⋅H2O. CaCl2⋅2H2O(aq) + K2C2O4⋅H2O(aq) --> CaC2O4⋅H2O(s) + 2KCl(aq) + 2H2O(l) starting material (SM) product Molar Mass (MM) g/mol: CaCl2⋅2H2O = 147.02 K2C2O4⋅H2O = 184.24 CaC2O4 = 128.10 Determine Mass ofK2C2O4⋅H2O(aq) in Salt Mixture in grams. Answer to 3 places after the decimal and include unit, g Do calculation all at once,...
When a 5.26-g sample of solid ammonium nitrate dissolves in 52.5
g of water in a coffee-cup calorimeter (see above figure) the
temperature falls from 24.00 oC to 17.20 oC.
Calculate H in kJ/mol NH4NO3 for
the solution process.
NH4NO3(s)
NH4+(aq) + NO3-(aq)
The specific heat of water is 4.18 J/g-K.
Hsolution = _________kJ/mol
NH4NO3.
A solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of the solid is dissolved in 50.0 g water, the freezing point is lowered by 5.50°C. What is the composition, by mass, of the solid? Mg(NO3)2 ?g NaNO3 ?g

A 1.225-g white solid mixture of [CaCl2
2H2O (147.02 g/mol) +
K2C2O4
H2O (184.24 g/mol)] was dissolved in 150 mL of deionized
water, heated and then cooled. The mass of the air-dried product
[CaC2O4
