4 moles as their raport is 4/2 or 2/1
A lot of cooking involves chemistry and is essentially a series of chemical reactions. Knowing about this kitchen chemistry can help you to understand much more about what’s happening – and why your recipes sometimes go wrong.Bananas turning brown is kitchen science.Why curry is hot uses chemical formulas.What happenes when meat cooks involves chemical formulas.Why popcorn pops inovopves chemical formulas.And,why honey is good for sore throats involves chemical formulas.
Answer:
(a) 0.25 mol
(b) 0.11 mol
(c) 8.77 mol
Explanation:
(a)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 1.00 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 298 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:

(b)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 0.296 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 200 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:

(c)
We use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 30 atm
V = Volume of the gas = 6.0 L
T = Temperature of the gas = 250 K
R = Gas constant =
n = number of moles = ?
Putting values in above equation, we get:
