Two vessels are labeled A and B. Bessel A contains NH3 gas at 68 C, and vessel B contains Ne gas at the same temperature. If the
average kinetic energy of NH3 is 7.1 x 10^-21 J / molecule at 70 C, calculate the root-mean-square speed of Ne atoms in m/s.
My main problem is in converting the average kinetic energy of NH3 at 70 C to average kinetic energy of NH3 at 68 C?

1 answer:
Answer:
Root mean square speed = 649.205m/s
Explanation:
The root mean square speed shows the connection between the average kinetic energy of molecules and the gas temperature. it is derived from the ideal gas equation and the average kinetic energy. Vrms = square root ( 3RT/M).

The amount of sugar is 2621 mg
Why?
The complete question is:
A 12.630 g milk chocolate bar is found to contain 8.315 g of sugar.
Part B. What will be the amount of sugar in milligrams if the size of the milk chocolate bar is reduced from 12.630 g to 4.000 g ?
To find the answer we have to determine first the amount of sugar in milligrams per gram of chocolate bar. We can find that by applying the following conversion factor:
Now, we have to determine the amount of sugar in milligrams if we had a chocolate bar with 4.000 g:
