Molecular Weight Calculations for SO2

The video tutorial explains how to calculate the molecular weight of sulfur dioxide (SO2). It begins by identifying the molecular weight of sulfur (32.07 grams/mole) and oxygen (16.00 grams/mole). Since there are two oxygen atoms in SO2, the weight of oxygen is doubled. The tutorial then adds these values to find the total molecular weight of SO2, which is 64.07 grams/mole. The video concludes with a sign-off from Dr. B.

What is the molecular weight of Sulfur (S) as found on the periodic table?

• 12.01 grams/mole

• 16.00 grams/mole

• 64.07 grams/mole

• 32.07 grams/mole

How many grams per mole is the molecular weight of a single Oxygen (O) atom?

• 32.07 grams/mole

• 16.00 grams/mole

• 12.01 grams/mole

• 8.00 grams/mole

Why do we multiply the molecular weight of Oxygen by 2 in the calculation for SO2?

• Because there are two sulfur atoms

• Because there are two oxygen atoms

• To convert to grams

• To adjust for temperature

What is the total molecular weight of SO2?

• 16.00 grams/mole

• 64.07 grams/mole

• 48.00 grams/mole

• 32.07 grams/mole

What is the first step in calculating the molecular weight of SO2?

• Convert the weights to kilograms

• Find the weight of sulfur on the periodic table

• Multiply the weight of oxygen by 2

• Add the weights of sulfur and oxygen
