Answer:
Explanation:
-mass of solute, density of solute, and volume of solution
-volume of solute, mass of solution, and density of solution
Answer:
Explanation:
The dilution formula is:

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.
Substitute:

Clear M₂ and compute:

Answer:
<h3>The answer is 2.65 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 2 g
density = 0.756 g/mL
So we have

We have the final answer as
<h3>2.65 mL</h3>
Hope this helps you
Answer:
B
Explanation:
This is because exothermic reactions occurs when bnds are formed, and involves the release of energy.
Endothermic reaction occur when bonds are broken,and involves absorption of energy.
