<h3>What is colligative property?</h3>
- Colligative properties in chemistry are those of a solution that depend on the amount of solute particles to solvent particles in a solution rather than the makeup of the individual particles.
- The number ratio can be connected to the several units used to measure a solution's concentration, including molarity, molality, normalcy (chemistry), etc.
- For ideal solutions, which are ones that have thermodynamic properties similar to those of an ideal gas, and for diluted actual solutions, the assumption that solution properties are independent of the type of solute particles is exact.
<h3>What factors affect colligative properties?</h3>
- A property of a solution is said to be collative if it depends simply on the proportion of solute to solvent particles in the solution and not on the nature of the solute.

Answer:
75 g
Step-by-step explanation:
<em>Step 1. </em>Calculate the molar mass of CaCO₃
Ca = 40.08
C = 12.01
3O = 3 × 16.00 = <u> 48.00
</u>
Total = 100.09 g/mol
<em>Step 2</em>. Calculate the mass of the pellet
Mass of CaCO₃ = 0.75 mol × (100.09 g/1 mol)
Mass of CaCO₃ = 75 g
Answer:
Explanation:
When determining empirical formulas of hydrates we have to find the mass of water which left the hydrate when heating The sample. This amount of water calculated will provide us with the correct ratio of moles water / moles anhydrate since moles water > moles anhydrate. The mistake might have been done while determining the water that left the sample so then we see and impropre result in ratios.
Answer:
A - 3
B - 6
Explanation:
The valency of hydrogen atom is +1
The valancy of an atom of other element combining with the hydrogen atom can be determined from the number of associated hydrogen.
when H combines with A, three atoms of hydrogen are used. Thus the valency of element A is -3
Now B combines with two molecules of A whose valency is -3
The valency of B would be twice the valency of element A i.e 6
if hydrogen combines with B, then the compound formed will be BH6
