Good day.
00:01
The topic is about malarity.
00:03
Malarity is a way of expressing concentration, which is solved as the ratio of the most of solute and the liters of the solution.
00:10
This problem, we are given with the molarity of nano3 solution, which is 4 .85 moles per liter, and the volume is 365 ml.
00:19
We wish to find the amount of nano3 that is dissolved in the solution in kilograms.
00:25
To start, let us solve for the moles of the solute in the given solution.
00:32
So from the formula for malarity, we have moles of solute is going to be solved as the molarity times the liters.
00:46
We note that the given volume here is in ml.
00:50
So to get its corresponding liters of the solution, we're going to divide this by 1000...
