Final answer:
To find the number of moles of perchlorate ions in 81.1 ml of 1.647 m magnesium perchlorate, you can use the formula: Moles = volume (in liters) x molarity. Converting 81.1 ml to liters (Divide by 1000): 81.1 ml = 0.0811 L. Using the given molarity of 1.647 M, you can calculate: Moles = 0.0811 L x 1.647 M = 0.1338 moles (rounded to 4 decimal places).
Step-by-step explanation:
To find the number of moles of perchlorate ions in 81.1 ml of 1.647 m magnesium perchlorate, we need to use the formula:
Moles = volume (in liters) x molarity
Converting 81.1 ml to liters (Divide by 1000): 81.1 ml = 0.0811 L
Using the given molarity of 1.647 M, we can calculate:
Moles = 0.0811 L x 1.647 M = 0.1338 moles (rounded to 4 decimal places)
