Answer:
0.39 mol
Explanation:
Considering the ideal gas equation as:
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
At same volume, for two situations, the above equation can be written as:-
Given ,
n₁ = 1.50 mol
n₂ = ?
P₁ = 3.75 atm
P₂ = 0.998 atm
T₁ = 21.7 ºC
T₂ = 28.1 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (21.7 + 273.15) K = 294.85 K
T₂ = (28.1 + 273.15) K = 301.25 K
Using above equation as:

Solving for n₂ , we get:
n₂ = 0.39 mol
Energy is the correct answer. I hope I helped you

True because they are organically made without any things that include chemicals
Answer:
9 mL.
Explanation:
Dosage of insulin is 90 mg
The concentration of insulin is 10 mg/mL
We need to find how many milliliters of the solution do you need to give the patient. It can be calculated as follows :

So, 9 mL of the solution is to be given to the patient.
