What is the change in the freezing point of water when 35g of sucrose is dissolved in 300g of water?
To determine the change in the freezing point of water when 35g of sucrose is dissolved in 300g of water, we can use the freezing point depression formula: ΔTf = i * Kf * m, where i is the van 't Hoff factor (1 for sucrose), Kf is the freezing point depression constant for water (1.86 °C kg/mol), and m is the molality of the solution. First, calculate the number of moles of sucrose: ( \text{moles} = \frac{35g}{342.3 g/mol} \approx 0.102 moles ). The mass of the solvent (water) in kg is 0.3 kg, so the molality ( m = \frac{0.102 moles}{0.3 kg} \approx 0.34 , mol/kg ). Thus, the change in freezing point is ( ΔTf = 1 * 1.86 °C kg/mol * 0.34 , mol/kg \approx 0.63 °C ). Therefore, the freezing point of the solution will decrease by approximately 0.63 °C.

How many molecules of sodium chloride in 15g of sodium chloride this atomic mass of sodium is 23gmol and of chlorine is 35gmol?
The formula unit of sodium chloride has the formula NaCl, showing that each molecular unit contains one atom of each of its constituent elements. Therefore, the mass of the formula unit is 23 plus 35 or 57 amu. Each amu for a compound contains Avagadro's number of molecules. Therefore, the answer to the problem is about (15/57) X 6.022 X 1023 = 4.3 X 1022.
When drying mushrooms what percent of weight will the mushroom lose?
Mushrooms loose 90% of there weight when drying so 3.5g of dry is equal to 35g fresh.
How do you prepare nesslers reagent?
To prepare Nessler's reagent, dissolve 7g of mercuric iodide and 35g of potassium iodide in distilled water, and then add 100g of potassium hydroxide pellets. Once the solution is clear, dilute it with water to make 1 liter of Nessler's reagent. This reagent is commonly used for detecting ammonia in solutions.
