determine the mass (g) of SO2 that is produced byt the reaction of 15g of CS2 according to the following equation:

CS2 + 3O2 = CO2 + 2SO2

To determine the mass of SO2 produced by the reaction, we need to calculate the molar mass of CS2, find the moles of CS2 present, and then use the stoichiometric coefficients to find the moles of SO2 produced. Finally, we can convert the moles of SO2 to grams using the molar mass of SO2. Let's go step-by-step:

Step 1: Calculate the molar mass of CS2:
The molar mass of carbon (C) is 12.01 g/mol, and the molar mass of sulfur (S) is 32.07 g/mol. To find the molar mass of CS2, we sum the molar masses of carbon and sulfur and multiply them by their respective subscripts in the formula.

Molar mass of CS2 = (12.01 g/mol * 1) + (32.07 g/mol * 2)
= 12.01 g/mol + 64.14 g/mol
= 76.15 g/mol

Step 2: Find the moles of CS2:
We can use the molar mass of CS2 to convert the given mass (15 g) to moles.

Moles of CS2 = Mass of CS2 / Molar mass of CS2
= 15 g / 76.15 g/mol
= 0.197 moles (rounded to three decimal places)

Step 3: Use the stoichiometric coefficients to find the moles of SO2.
From the balanced equation, we see that the ratio of moles of CS2 to SO2 is 1:2. Therefore, we can calculate the moles of SO2 produced using this ratio.

Moles of SO2 = Moles of CS2 * (2 moles of SO2 / 1 mole of CS2)
= 0.197 moles * (2/1)
= 0.394 moles (rounded to three decimal places)

Step 4: Convert the moles of SO2 to grams:
To convert moles of SO2 to grams, we need to multiply the moles by the molar mass of SO2.

Molar mass of SO2 = (32.07 g/mol * 2) + (16.00 g/mol * 1)
= 64.14 g/mol + 16.00 g/mol
= 80.14 g/mol

Mass of SO2 = Moles of SO2 * Molar mass of SO2
= 0.394 moles * 80.14 g/mol
= 31.57 grams (rounded to two decimal places)

Therefore, the mass of SO2 produced by the reaction is approximately 31.57 grams.

To determine the mass of SO2 produced, we need to use stoichiometry, which is a way of calculating the number of moles and the mass relationship between reactants and products in a chemical equation.

Here's how you can calculate the mass of SO2 produced:

1. Convert the given mass of CS2 to moles. To do this, you need to know the molar mass of CS2, which is carbon (C) with a molar mass of 12.01 g/mol and sulfur (S) with a molar mass of 32.07 g/mol. The molar mass of CS2 is then 12.01 g/mol + 2(32.07 g/mol) = 76.15 g/mol.

Given mass of CS2 = 15 g
Moles of CS2 = Given mass / Molar mass = 15 g / 76.15 g/mol

2. Set up a stoichiometric ratio using the balanced equation. From the balanced equation, we see that 1 mole of CS2 produces 2 moles of SO2.

Moles of SO2 = Moles of CS2 × (2 moles SO2 / 1 mole CS2)

3. Convert the moles of SO2 to mass. To do this, you need to know the molar mass of SO2, which is sulfur (S) with a molar mass of 32.07 g/mol and oxygen (O) with a molar mass of 16.00 g/mol. The molar mass of SO2 is then 32.07 g/mol + 2(16.00 g/mol) = 64.07 g/mol.

Mass of SO2 = Moles of SO2 × Molar mass = Moles of SO2 × 64.07 g/mol

Now, you can substitute the values and calculate the mass of SO2:

Moles of CS2 = 15 g / 76.15 g/mol
Moles of SO2 = (15 g / 76.15 g/mol) × (2 moles SO2 / 1 mole CS2)
Mass of SO2 = (15 g / 76.15 g/mol) × (2 moles SO2 / 1 mole CS2) × 64.07 g/mol

Calculate the result to determine the mass of SO2 produced.

convert 15g CS2 to moles

each mole of CS2 produces 2 moles of SO2
now convert those moles back to g of SO2
