Answer:
mmoles of potassium ion = 75.264 mmoles
mmoles of dichromate ion = 37.632 mmoles
Explanation:
Considering:-
For :
Molarity = 0.0840 M
Volume = 448 mL
The mmoles of are;-
In 1 mmole of , 2 mmoles of potassium ion and 1 mmole of dichromate ion is present.
In 37.632 mmole of , 2*37.632 mmoles of potassium ion and 1*37.632 mmole of dichromate ion is present.
<u>mmoles of potassium ion = 75.264 mmoles</u>
<u>mmoles of dichromate ion = 37.632 mmoles</u>

<h3>What is the law of conservation of mass?</h3>
We know that according to the law of the conservation of mass, the mass of an object can neither be created nor destroyed but it can be changed from one form to the other.
Looking at this law, we know that the mass would not change even after the time that the wax must have hardened. The total mass of the wax would have to be a constant.
Total mass would now be;
Mass of the wax + mass of the container
= 3 g + 15 g
= 18 g
Weight = 18/1000 * 9.8 m/s^2
= 0.18 N
