What is the molarity of a kmno4 solution if there are 4.0000 g of kmno4 in 1 liter of solution?

Hey there!:

Molar mass KMnO4 = 158.0339 g/mol

Number of moles :

n = m / mm

n = 4.0000 / 158.0339 => 0.0253 moles of KMnO4

Volume of solution = 1 liter

Therefore:

Molarity = n /  V ( L )

Molarity = 0.0253 / 1

Molarity = 0.0253 M

Hope that helps!

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

the increase of protons   hope this
