The number of moles of K_(2)Cr_(2)O_(7) reduced by 1 mol of Sn^(2+) ions is. 13mol ofCr2O2-7=1mol ofSn2+.

## How many number of moles of K2Cr2O7 are reduced by 1 mole?

-Now, we need to write the balanced net equation of the above reaction. -It is clear from the balanced net equation that one mole $C{{r}_{2}}{{O}_{7}}^{2- }$ is reduced by three moles $S{{n}^{2+}}$ . Hence the correct answer is option A.

## How many moles are in K2Cr2O7?

The SI base unit for amount of substance is the mole. 1 grams K2Cr2O7 is equal to 0.0033992262001478 mole.

## How many moles of K2Cr2O7 is required to oxidise?

That is, each mole of K2Cr2O7 oxidises 2 moles of ferrous sulphate. Hence, to oxidize 2 moles of FeSO4, only 1 mole of K2Cr2O7 is required.

## How many moles are in H2O?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

## What is the molar mass of k2cr2o7?

First, you need to find the molar mass of tin which is 118.7100 g/mol which is found on the periodic table.

## How many moles of k2cr2o7 are required to oxidize 1mole of ferric oxalate?

Explanation: The following equations are essential in the answering of the question. In Acidic medium. We therefore need 0.5moles to oxidize one mole of ferrous oxalate.

## How many moles of KMnO4 react with one mole of ferrous oxalate in acidic medium?

hence 3/5 moles of KMnO4 of KMnO4 will be needed to react completely with one mole of ferrous oxalate in acidic solution…..
