Around 24.85 miles per hour
, divide the length value by 1.60
Answer:
The answer to your question is 308.1 g of KmNO₄
Explanation:
Data
Volume = 6 L
Concentration = 0.325 M
Molar mass of Potassium permanganate = 39 + 55 + (16 x 4) = 158 g
Process
1.- Calculate the moles of KMnO₄
Formula
Molarity = moles/volume
moles = molarity x volume
moles = 0.325 x 6
moles = 1.95
2.- Calculate the grams of KMnO₄
158 g KMnO₄ ------------------ 1 mol
x ------------------ 1.95
x = (1.95 x 158)/1
x = 308.1 g

In order to know the number of moles from the given mass, the conversion factor to be used is the average atomic mass of Calcium which is equal to 40.08 g/mol. But first, let's convert mass from grams to kilograms knowing that there are 1,000 g in every 1 kg.
Mass = 351 kg * 1,000g/1 kg = 351,000 grams
Number of moles = 351,000 g * 1 mol/40.08 g = 8,757.5 moles Calcium
