4.003 is the mass of helium gas
Answer:
Explanation:
Hello,
In this case, since the entropy of vaporization is defined in terms of the enthalpy of vaporization and the boiling point of the given substance, nitrous oxide, as shown below:
Solving for the boiling point of nitrous oxide, we obtain:
Which in degree Celsius is also:
Best regards.
Answer:
Mass of ethane which is contained in 50 mL is 4.25 g
Explanation:
13.9% by mass, means that in 100 g of solution, we have 13.9 grams of solute.
Density of solution is 0.611 g/mL
Volume of solution is 50 mL
Density = mass of solution / 50mL
0.611 g/mL . 50 mL = mass of solution → 30.55 g
Now, the rule of three.
In 100 grams of solution we have 13.9 grams of solute
30.5 grams of solution we have (30.55 . 13.9) / 100 = 4.25 g
Answer:
The correct answer is C:
Kumho Tire Co. Ltd V. Daubert
Explanation:
In this case, the appellant (Daubert) has sued Kumho Tire Co. Ltd (the defendant) when 3 months prior the right rear tyre of his car exploded while the car was in motion killing a passenger and injuring others severely.
The appellant employed the services of an expert who had worked for 10 years with Michelin to give his opinion as having studied the attributes of the tire technology.
In a counter-argument, the defendant rather than dispute the opinion of the expert urged the court to exclude it as evidence because his methodology didn't conform to the requirements of the Law as given in Rule 702 of the Federal Rules of Evidence.
True to the defendants' position, the Law by the ruling in Daubert v Merrell Dow Pharmaceuticals required that for the opinion to count, it had to be scientifically correct. It was hence excluded as evidence in the case.
Cheers!
