Answer:
V2= 5L
Explanation:
P1= 500kPa, V1= 3L, P2= 300kPa, V2=?
Applying Boyle's law
P1V1=P2V2
(500*3)= (300*V2)
V2= 5L
Answer:
e. 81.0%
Explanation:
Morphine has Molar mass = 285.34 g/mol
Also, number of males of Morphine = Number of moles of HCl
(At equivalence point )
Now, number of moles of HCl = Molarity × volume
=0.01 mol × 2.84×10^(-3) L
= 2.84×10^(-5) mol
therefore number of moles of morphine= 2.85×10^(-5)
Mass of Morphine= No. of moles × molar mass
= 2.84×10^(-5)×285.34 g/mol
= 0.0081 g
= 8.1 mg
therefore
percentage of morphine = mass of morphine/ mass of powder×100%
= 8.1/10×100% = 81.0%
hence option e is correct.
