Sulfur dioxide gas (SO2) and oxygen gas (O2) react to form the liquid product of sulfur trioxide (SO3). How much sulfur dioxide
taurus [48]
1) Balanced chemical equation:

2SO2 (g) +  O2 (g) -> 2SO3 (l)

2) Molar ratios

2 mol SO2 : 1 mol O2 : 2 mol SO3

3) Convert 6.00 g O2 to moles

number of moles = mass in grams / molar mass

number of moles = 6.00 g / 32 g/mol = 0.1875 mol O2.

4) Use proportions with the molar ratios

=> 2 moles SO2 / 1 mol O2 = x / 0.1875 mol O2

=> x = 0.1875 mol O2 * 2 mol SO2 / 1 mol O2 = 0.375 mol SO2.

5) Convert 0.375 mol SO2 to grams

mass in grams = number of moles * molar mass

molar mass SO2 = 32 g/mol + 2*16 g/mol = 64 g/mol

=> mass SO2 = 0.375 mol * 64 g / mol = 24.0 g

Answer: 24.0 g of SO2 are needed to react completely with 6.00 g O2.

1. The molecule of Aspirin C_{9}*H_{8} * O_{4} contains 9C atomsatoms, and 4 Oxygen atomsHow are we using the molecular formula
tatiyna

The mass can be obtained from the molar mass when the number of moles is known.

<h3>What is molecular formular?</h3>

The molecular formlar is the formula of the compound that shows the number of atoms of each element that is present in the molecule. Asprin is a moecule that has the molecular formula C9H8O4.

To use the molecular formula to determine weight, we have to know the number of moles involved.

Mass = number of moles * molar mass.
