Answer:
Explanation:
Hello,
In this case, it is convenient to compute the car's mileage in km/L as follows:
In such a way, since the distance is measured to be 250 km, the volume requirement is:
Regards.
A substance in a solid phase is relatively rigid, has a definite volume and shape.
<span>The atoms or molecules that comprise a solid are packed close together and are not compressible.<span>Because all solids have some thermal energy, its atoms do vibrate. However, this movement is very small and very rapid, and cannot be observed under ordinary conditions.</span></span>
Answer:
0.48atm
Explanation:
Firstly, we need to know the mole ratio of the oxygen gas involved. To do this, we simply place the number of moles of the oxygen over the sum of both gases.
This would be 3/(3+7) = 0.3
Now, to get the partial pressure contributed by the oxygen gas, we simply multiply the 0.3 by the total pressure
Hence, the partial pressure of oxygen = the mole fraction of oxygen * the total pressure.
= 0.3 * 1.6 = 0.48atm
