Question

what is a molarity of a solution in 9.8 moles of sodium chloride NaCL is dissolved in water to a final volume 3.2 l

Answer 1

Answer: 3.1 including s.f.

Step-by-step explanation:

The original number is 3.0625 but it needs the same significant figure so it is 3.1

Answer 2

Answer:
molarity = 3.0625 M

Step-by-step explanation:
Molarity can be calculated using the following rule:
molarity = number of moles of solute / volume of solution

We are given that:
number of moles of solute = 9.8 moles
volume of solution = 3.2 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = 9.8 / 3.2
molarity = 3.0625 M

Hope this helps :)
