Answer is: 0,275 moles of oxygen are consumed.
Chemical reaction: 2Mg + O₂ → 2MgO.
n(Mg) = 0,550 mol.
n(O₂) = ?
from chemical reaction: n(Mg) : n(O₂) = 2 : 1.
0,550 mol : n(O₂) = 2 : 1.
2n(O₂) = 0,550 mol.
n(O₂) = 0,275 mol.
n - amount of substance.

<u>Answer:</u> 0.275 moles of oxygen gas is consumed in the reaction.

<u>Explanation:</u>

We are given:

Moles of magnesium = 0.550 moles

For the given chemical reaction:

2Mg(s)+O_2(g)\rightarrow 2MgO(s)

By Stoichiometry of the reaction:

2 moles of magnesium reacts with 1 mole of oxygen gas.

So, 0.550 moles of magnesium will react with = \frac{1}{2}\times 0.550=0.275mol of oxygen gas.

Hence, 0.275 moles of oxygen gas is consumed in the reaction.

What would be the mass in grams of 1.204 x 1024 molecules of sulfur dioxide
melomori [17]

Answer:

mass of sulfur = 96 g

Explanation:

no of moles of sulfur dioxide in 1.204\times 10^{24} molecules = \frac{1.204\times 10^{24}}{avagadro number }= \frac{1.204\times 10^{24}}{6.023\times 10^{23}}

                                       = 2 moles

therefore mass of sulfur dioxide = moles×atomic number

                                                      =2×(16+32)

                                                      =96
