You didn't give the reaction.
To calculate the molecules of oxygen required to react with 28.4g of sulfur, we need to determine the mole ratio between sulfur and oxygen in the given reaction. This mole ratio is obtained from the balanced chemical equation.
Let's assume the balanced chemical equation for the reaction is:
Sulfur + Oxygen -> Product
From the equation, we need to determine the stoichiometric ratio between sulfur and oxygen. Given that the molar mass of sulfur is 32.06 g/mol and the molar mass of oxygen is 16.00 g/mol, we can calculate the moles of sulfur first.
Moles of sulfur = mass of sulfur / molar mass of sulfur
= 28.4 g / 32.06 g/mol
≈ 0.885 mol (rounded to three significant figures)
Now, using the balanced chemical equation, we can determine the ratio of sulfur to oxygen. Let's assume it is 1: x.
1 mol of sulfur reacts with x mol of oxygen.
Therefore, moles of oxygen required = moles of sulfur * x
= 0.885 mol * x
To find the value of x, we need additional information from the question or the given reaction. Without that information, we cannot calculate the exact number of oxygen molecules required.
However, we can still compare the provided answer choices with the calculated moles of oxygen required and select the closest option:
a) 1.60 * 10^24 molecules
b) 3.56 * 10^23 molecules
c) 2.67 * 10^23 molecules
d) 5.33 * 10^23 molecules
e) 8.00 * 10^23 molecules
Based on the calculated value of moles of oxygen required (0.885 mol), none of the options provided closely match this value. Therefore, we cannot determine the exact number of oxygen molecules required without additional information.
