write a balanced reaction for 50.92 grams of carbon disulfide,including molar masses. then calculate the moles of carbon disulfide and oxygen. now find the mass of oxygen consumed in the reastion.

HELP!!!

CS2 + 3O2 ==> CO2 + 2SO2

Your question isn't completely clear as to the reaction. I assume the above is it. Now you write in what you know and tell us what you don't understand.

1 mole of CS2 = 12.011 + 32.066x2 = 76.143 g/mol

(50.92 g) / (76.143 g/mol) = 0.66874 moles CS2

Based on the chemical equation DrBob gave you for the combustion of CS2,
(0.66874 mol CS2)(3 mol O2 / 1 mol CS2) = ___moles O2

To get the mass (grams) of O2 consumed in the reaction, multiply the moles of O2 by the molar mass of O2.

To write a balanced reaction equation for the combustion of carbon disulfide (CS2), we need to know that combustion involves reacting a substance with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The balanced equation for the combustion of CS2 can be written as:

CS2 + 3O2 → CO2 + 2SO2

Now, let's proceed step by step to calculate the moles of carbon disulfide and oxygen, as well as the mass of oxygen consumed in the reaction.

1. Calculate moles of CS2:
First, we need to determine the molecular weight (molar mass) of carbon disulfide (CS2). The molar mass of carbon (C) is approximately 12.01 g/mol, and the molar mass of sulfur (S) is approximately 32.07 g/mol. Since CS2 contains two sulfur atoms, the molar mass of CS2 is:

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

Now, divide the given mass of carbon disulfide (50.92 g) by its molar mass to calculate the moles:

Moles of CS2 = Mass of CS2 / Molar mass of CS2
= 50.92 g / 76.15 g/mol

2. Calculate moles of oxygen:
From the balanced equation, we can see that the stoichiometric ratio between CS2 and O2 is 1:3. Therefore, the moles of oxygen consumed will be three times the moles of CS2:

Moles of O2 = Moles of CS2 × 3

3. Find the mass of oxygen consumed:
To determine the mass of oxygen consumed, we need to know the molar mass of oxygen (O2), which is approximately 32.00 g/mol. Then, multiply the moles of oxygen by its molar mass:

Mass of oxygen consumed = Moles of O2 × Molar mass of O2

By following these steps, you should be able to find the balanced reaction equation, calculate the moles of carbon disulfide and oxygen, and determine the mass of oxygen consumed in the reaction.
