Question

How many liters of carbon dioxide can be produced if 37.8 grams of carbon disulfide react with excess oxygen gas at 28.85 degrees Celsius and 1.02 atmospheres?

CS2(l) + 3O2(g) yields CO2(g) + 2SO2(g)


2.78 liters
5.95 liters
12.1 liters
11.9 liters

Answer 3

Your first step is to take the amount of carbon disulfide and divide be the molar mass so 37.8/ 76.14= number of moles of carbon disulfide

Answer 4

Once you find the moles of carbon disulfide you relate it to the carbon dioxide the stoichimometric coefficients are both 1:1 so the moles of carbon disulfide are the same as the carbon dioxide

Answer 5

Since you have the moles of carbon dioxide you can use the ideal gas formula PV=nRT
But first you have to switch Celsius to Kalvin. To do this you take 28.85 and add 273.15 to get your temperature as 302K

Answer 6

P is pressure so that's 1.02 atm
V is the volume you are trying to find
n is the moles of carbon dioxide
R is the ideal gas constant 0.082
T is the temperature in Kalvin so that's the 302K

Are you understanding what I put? @jammy987

Answer 8

ok so that answer would be c? @taramgrant0543664

Answer 9

Yes it would be c
