Final answer:
To determine the number of moles of solute in a 9.03 M solution with a volume of 15.8 L, multiply the molarity (9.03 mol/L) by the volume of the solution, resulting in 142.674 moles of solute.
Step-by-step explanation:
To find out how many moles of solute are in a 9.03 M solution with a volume of 15.8 L, we need to use the definition of molarity, which is moles of solute per liter of solution (mol/L). The formula to find the number of moles of solute is:
moles of solute = molarity × volume
In this case, the molarity is 9.03 mol/L, and the volume of the solution is 15.8 L. By multiplying these two values, we get:
moles of solute = 9.03 mol/L × 15.8 L
This gives us the total moles of solute in the solution:
moles of solute= 142.674 mol
