The answer is 12.5 mL.
Solution:
<u>M, 6.00M V₁ =?</u>
M2 = 3.00M, V₂ = 25.0mL
<u>M1V1 = M2 V2/M1</u>
V1 = M2V2 M,
V1 = 25.0X3.00/6.00
∴ V1 = 12.5 mL
The initial concentration of the resulting solution is 2 molar which is the volume multiplied by the concentration. The volume of the starting solution is therefore 2,500 ml × 2.25 mol. Calculate the number of moles of HCl dissolved in a given volume of acid by reacting an acid with CaCO3.
This is essentially a double exchange reaction with the decomposition of one of the products. To determine the amount of stock solution required divide the number of moles of glucose by the molarity of the stock solution.

Answer:
115N
Explanation:
your friend and you push the car at the same time at the same direction so you add the force your friend is using and the force you’re using so: 60+55=115N
Your answer is A. At least I think
If one is dilute, there is more water than substance dissolved in it. If it is concentrated, it has dissolved the maximum amount of the solvent dissolved in it.
