# How many moles of O2 are needed to make one mole of No?

## How many moles of O2 are needed to make one mole of No?

2 moles
This equation tells us that for every 2 moles of NO2 formed ; we require 1 mole of O2 .

## How many moles of O2 are needed to react completely with 1.2 moles C2H6?

Question: Use the balanced equation to answer the question. 2 C2H6(g) + 5 O2(g)-→ 4 CO(g) + 6 H2O(g) How many moles of 02 are needed to react completely with 2.4 moles of C2H6? mol O2.

How many moles of oxygen are needed for the reaction?

This means that, in order for the reaction to take place, every mole of the former will require 9 moles of the latter. Therefore, one mole of 3-methylpent-2-ene will require nine moles of oxygen in order to react completely.

### How many moles of oxygen are needed to completely combust the ethene?

Therefore, assuming complete combustion, one mole of ethane will react with 7/2 (3.5) moles of oxygen.

### How many moles of O2 are needed in a reaction to make 4 moles of H2O?

Further, that you need 2 moles of hydrogen for each mole of oxygen (2:1). So, for 4 moles of hydrogen you will need 2 moles of oxygen to get 4 moles of water. Two moles of O2.

What is the mass of 1.5 moles of CO2?

66 g.
m = 66 g. Hence the mass of 1.5 moles of \$C{{O}_{2}}\$ is 66 g.

#### How many moles are in 12.0 grams of o2?

0.375 moles
Therefore, 12 g of oxygen gas has 0.375 moles.

#### How do you calculate 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.

How many moles of O2 are required for the complete combustion of propane?

5 of O2 are required for complete combustion of one mole of propane.

## How many moles of oxygen are needed to balance the combustion of ethene?

So, we need 3.5mol of O2 for the complete combustion of 1mol of ethane.

## How many moles of O2 are needed to react with C2H6?

Multiply the given moles C2H6 by the mole ratio between O2 and C2H6 in the balanced equation, so that moles C2H6 cancel, leaving moles O2. ~11 moles of O2 are required to react completely with 3.2 moles of C2H6.

How many moles are in 8 grams of O2?

One mole of O2 has 32g so 8 grams are equal to 0,25 moles. Now lets set a proportion 2 moles (H2):1 mole (O2)=n:0,25 moles (O2). When you solve a proportion you get n=0,5 moles.
