Question

More Gas Stoichiometry. -.- Will fan and medal.

Assume that 8.5 L of iodine gas (I2) are produced at STP according to the following balanced equation:

2KI(aq) + Cl2(g) → 2KCl(aq) + I2(g)

How many moles of I2 are produced?
How many moles of Cl2 are used?
How many grams of Cl2 (g) are used?

Answer 1

e standard temperature is 273 K (0° Celsius) and the standard pressure is 1 atm pressure. At STP, one mole of gas occupies 22.4 L of volume (molar volume)

Answer 2

1-->22.4 Litres
x-->8.5 Litres
8.5*1/22.4=0.380 mol
Look at the mole ratio of Cl2:I2 in the balanced chemical equation, you would realize that its 1:1, so they share the same number of moles.
Use Number of moles=mass(g)/Molar Mass(g/mol)
0.380*(35.5*2)=mass

Answer 3

Good job @Abmon98 :)
do u get it @Catseyeglint911 ?

Answer 4

Just got on to reply a few minutes ago, I had to take care of a quiz yesterday then shut down, but yes I do now.
