Weight of solute = 45 g and weight of solvent = 55 g
M.wt of solute = 180 P⁰ = 526 mmHg
number of moles of solute = 45 / 180 = 0.25 mol
number of moles of solvent = 55 / 18 = 3.05 mol
According to Rault's law:

= 0.25 / (0.25 + 3.05)

Answer:
HCl
Explanation:
HCl is an acid.
It gives H+ ions when dissolve in water
Answer:
The radius of the centrifuge.
Explanation:
Hello,
Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.
Best regards.
Producer. Hope this helps!
