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.
The electronic configuration of the elements which share the group, must have the last electron in same block..
The vapour pressure of water at 61°C is 1.28x10⁻³
Vapour pressure of a pure compound is the pressure characteristic at any given temperature of a vapour in equilibrium with its liquid or solid form
Kp=P H 2O =0.0313.
But
K p=K c(RT)
Δn=K c
(RT) because Δn=1.
Substitute values,
0.0313=K c (0.0821×298)
K c =1.28×10 −3 .
