# How many moles of copper must react to form?

Contents

## How do you calculate how many moles needed to react?

Determine the number of moles needed to react by multiplying by moles of the known substance by the stoichiometric ratio of the unknown substance to the known substance.

3:2:1.

## How many moles of silver chloride are produced?

tells you that when 1 mole of barium chloride is consumed by the reaction, 2 moles of silver chloride are produced.

## How many moles of oxygen are produced when 2 mol of potassium chlorate kclo3 decompose 1?

This tells us that for every 2 moles of potassium chlorate that are decomposed, then 3 moles of oxygen gas is produced.

## How do you find the moles of a product formed?

In order to calculate the moles of a product, you must know the mass of the product, and its molar mass (g/mol), which is the mass of one mole of of the product. You then divide the mass of the product by its molar mass.

## What is the mole ratio of Fe to Fe2O3?

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt. of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75moles Fe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

## What is the molar ratio between Fe and h2o?

These mole ratios tell you that regardless of how many moles of one reactant you have, there will always be a 1:2 mole ratio between them. Similarly, the reaction will always produce twice as many moles of water than of carbon dioxide because the two reactants are in a 2:1 mole ratio.

## What is the mole ratio of water to h3po4?

Explanation: And so the molar ration is 6:1 , water:phosphoric acid ……. And you have written the stoichiometrically balanced chemical reaction to inform you.

## How many moles of water are produced when 3.45 moles of KMnO4 react give your answer to the nearest 0.1 moles?

The reaction of 3.45 mol of KMnO4 produces 6.9 mol of water.

## How many grams of AgCl are produced after the reaction?

Therefore, the mass of AgCl formed by the reaction is 0.84 g.

## How many grams of AgCl will be formed?

Molar mass of AgCl = (108 + 35.5) g/mol = 143.5 g/mol. So, the mass of AgCl produced = (0.03 × 143.5) g = 4.305 g.

## How many moles of oxygen are produced when 2 mol of potassium chlorate decomposes?

The reaction will produce 3 moles of oxygen gas for every 2 moles of potassium chlorate that decompose. This will be the theoretical yield of the reaction, i.e. what you get when the reaction has a 100% yield.

## How many moles are in potassium chlorate?

The answer is 122.5495. We assume you are converting between grams Potassium Chlorate and mole. You can view more details on each measurement unit: molecular weight of Potassium Chlorate or mol The molecular formula for Potassium Chlorate is KClO3. The SI base unit for amount of substance is the mole.

## How many moles of oxygen are produced if 4 moles of potassium chlorate decomposes?

Therefore, 4 moles of potassium chlorate must be used to produce 6 moles of oxygen gas.
