How many grams of potassium K are in 100 g of Kmno₄?

In one mole or 166 g of KI, 23.55% of it is K. Therefore, in 100 grams of KI , 23.55% of it would be K, so 23.55 g of potassium are in 100 g sample of KI. Another way to do it is setting up a proportion.

Why do we convert moles to grams?

When substances react, they do so in simple ratios of moles. … Balances DO NOT give readings in moles. So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances.

How many number of moles are equivalent to 8 gram of Co2?

The molar mass of cobalt is 58.93 g/mol. So assuming it forms diatomic molecules, the molar mass of Co2 would be 117.86 g/mol.

How do you make 0.1 KMnO4?

Potassium Permanganate 0.1 N: Dissolve 3.3 g of reagent grade potassium permanganate (KmnO4) in 1 L of purified water and heat on a steam bath for two hrs. Cover and allow to stand for 24 hrs. Filter through a fine porosity sintered glass crucible, discarding the first 25 mL.
