Mg also burns in carbon dioxide. In this case, Mg reacts with CO₂ to produce MgO and solid Carbon (C(s)). How many grams of CO₂ are needed to consume 1.00 g of Mg

The mass of needed is, 0.915 grams.

Explanation : Given,

Mass of = 1.00 g

Molar mass of = 24 g/mol

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical equation is:

From the balanced reaction we conclude that

As, 2 mole of react with 1 mole of

So, 0.0417 moles of react with moles of

Now we have to calculate the mass of

Molar mass of = 44 g/mole

Therefore, the mass of needed is, 0.915 grams.

the maximum mass of nh3 is nh3 in grams
