Question

According to your calculations a reaction should yield 5.67 g of oxygen O2. What do you expect the volume to be at 23 degrees C and 0.985 atm?

I got the all the amounts

5.67 g
23 degrees C = 296 K
.985 atm

And use the ideal gas law

Can you help me out by starting it
again

Answer 1

Same as last question. No need for me to type all that again.
mols = grams/molar mass = 5.67/32
Don't forget to change T to Kelvin.

Answer 2

.985(V)=.177(.0821)(296)=

Same thing do you multiply and then divide by .985

Answer 3

yes.
