How many moles of Co2 will be produced if 9.0 moles of O2 completely react?

1 answer:

8 0

It depends on what was being combusted.

Supposing the simplest case, where carbon is being burnt:

C + O2 → CO2

(9.0 mol O2) x (1 mol CO2 / 1 mol O2) = 9.0 mol CO2

The answer would be different if the fuel contained any oxygen atoms, for example, alcohol.

When you need to produce a variety of diluted solutions of a solute, you can dilute a series of stock solutions. A stock solutio

8090 [49]

Answer:

Volume of stock solution needed = 6.0299 mL

Explanation:

Dilution consists of lowering the amount of solute per unit volume of solution. It is achieved by adding more diluent to the same amount of solute.

This is deduced when thinking that both the dissolution at the beginning and at the end will have the same amount of moles.

Data:

M1 = 6.01 M stock solution concentration
