What is the molality of a solution that contains 2 moles of glycerin and dissolved in 1000 g of water?
Moles of solute/ kg of solvent = 2 molal solution
What does solution mean in geography terms?
A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent. The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of molecular size.
When a certain amount of calcium chloride (CaCl2) was dissolved 100.g of water the boiling point rose from 100.0C to 104.4C calculate the molality of this solution.?
Delta T = imKI = van't Hoff factor = 3 for CaCl2 m = molality = moles solute/kg solvent = ? K = boiling point constant for water = 0.512 Delta T = change in temperature = 4.4 deg C Plug in the values and solve for m
Is sugar dissolved in water is it a mixture but not a solution?
1. Sugar dissolved in water is a homogeneous solution.2. A solution is a form of mixture.
When sugar is dissolved in water to form a sugar solution what name do we give to the water?

What is a mixture composed of a solute dissolved in a solvent that may or may not contain water?
A solution or mixture.
What is the molality of a solution composed of 38.0 g of cane sugar (C12H 22O11) dissolved in 175 g of water?
molality = moles solute/kg solvent moles solute = 38.0g x 1 mol/342 g = 0.111 moles kg solvent = 175 g x 1kg/1000g = 0.175 kg molality = 0.111 moles/0.175 kg = 0.635 m
What is the molality of a solution of 90 grams of glucose C6H12OSUB6 dissolved in 800 grams of water?
first determine the number ofmoles dissolved in given solution then .5 moles moles dissolved in 800g. as comparison with 1000g of water, we know 100g of water dissolve only.1 moles of a glucose so we .7moles of glucose dissolve in 800g.

When can SUGAR no longer be dissolved in water?
at 250C the maximum solubility of sucrose, a common form of sugar, is 200g/100ml water or at a molality of 2. However, a supersaturated solution would be able to hold more sugar.
