Determine the solubility of 2.15g of N2(g) at 35°C dissolved in 3.0L of solvent.
1. A solution generally consists of two parts, a solute that is dissolved and a solvent that the solute is dissolved into. For example, sugar is a solute that is dissolved into the solvent water. In the Solubility and Temperature Gizmo, you will study how temperature affects how much solute will dissolve in a solution To begin, check that Potassium nitrate is selected, and the Temp. of the water is 20 °C. a. In this solution, what is the solute?...
Calculate the Kf of a solvent when 50.0 g of NaCl (58.44 g/mol) is dissolved in 250.g of solvent and lowers the freezing point by 6.36°C. (Assume that the solute completely dissociates.) O 0.68 °C/m O 1.36 °C/m O 1.86 °C/m O 0.93 °C/m
how much C2H6 would need to be dissolved in 250 g of an unknown solvent to lower its fp by 1.26 C? kf= 5.56 c/m
Determine the solubility of N2 in water exposed to air at 25°C if the atmospheric pressure is 1.2 atm. Assume that the mole fraction of nitrogen is 0.78 in air and the Henry's law constant for nitrogen in water at this temperature is 6.1 × 10-4 M/atm.
When (8.61x10^1) g of a non-electrolyte is dissolved in (5.3100x10^2) g of a solvent (with Kb = 0.416°C/m) the boiling point of the solution is 1.50°C higher than the boiling point of the pure solvent. What is the molar mass (in g/mol) of the non- electrolyte solute? Enter your answer in scientific notation with 3 sig figs. Do not include any units in your answer. Do not round any intermediate calculations. Note: Your answer is assumed to be reduced to...
Given a solubility data, determine the appropriate solvent to use for recrystallization. please give an example of data and a way to determine appropriate solvent to use for recrystallization. This is needed for the purpose of understanding the concept
Question 10 (4 points) The solubility of N2 in water is 1.75 x 10-2 g/L at 20°C and 1.0 atm. What is the solubility of N2(in g/L) from air at 20°C and 1.00 atm total pressure(where the pressure of the nitrogen is 0.781 atm)? 2.24 x 10-2 g/L 1.62 g/L 0 1.37 x 10-2 g/L 0 2.24 g/L 1.62 x 10-2 g/L
The typical or standard unit used for solubility is g solute/100g of solvent (water, in this case). Give a calculation below for converting from 4.15g of solute X in 12.35g of water to g/100g of water.
