The concentration of the solute in the solution is given by concentration units. Most used unit in Chemistry is molarity. Answer and Explanation: For 490 mL of a sodium nitrate 0.66 M solution, we have to read the concentration unit. In doing so, we can see...
Molality is a way to express the concentration of a solution. Molality depends on the amount of moles of dissolved in the solution divided by the mass of the solvent. Temperature doesn't affect the molality of a solution because moles of...
Because atoms become more massive as you move from lower to higher atomic numbers in the periodic table, molar masses vary enormously, with that of uranium being over 200 times that of hydrogen.Moles and Equivalents The equivalent unit was introduced to account for the fact that when solutes di...
An isotonic solution has the same tonicity on both sides of the membrane. The cells in your body have a 300 milliosmolar concentration of non-penetrating solutes, so they are isotonic to their environment as long as the interstitial fluid has a similar concentration. A hypertonic solution would...
In simple words, we can say that the mole fraction is the ratio of the mole of a solvent to the total number of moles. Use of Mole Fraction Equation This formula is easy to use if you know the number of moles of all the solutes and solvents. For illustration, suppose yo...
Concentrations of substances in solutions can be expressed in grams per 100 milliliters which is an example of percent weight by volume. The concentration can be expressed this way because some solutes are known or prepared using the solid form and the volume...
If the freezing point depression of water is -1.86 degrees/m, what would be the freezing point of this solution?How do you find the freezing point of pure water from the freezing point depression equation?The freezing point of a solution will ___ and the boiling point will...
It can do this either by increasing the amount of water in plasma or by excreting the molecules and matter contributing to the increased concentration of solutes in plasma; more on these processes shortly. The main contributors to serum osmolality are sodium ions (Na+), blood glucose (C6H12O6)...
What is the molar solubility of it in water. What happens if a solute is added to a saturated solution? What can be sources of error in a laboratory investigation dealing with the factors that affect the solubility of a solute? How does concentration affect the rate of reaction? C...
1. Explain why water is such a good solvent for so many different solutes? 2. Why should solutes be added to water rather than water added to solutes ? For a multiple solvent recrystallization- explain why and how this technique...
