A sample of neon has a volume of 75.8 L at STP. Calculate the number of moles​

Chemistry
1 answer:

8 0

Answer:

3.38 moles of neon

Explanation:

First you have to multiply the volume (75.8 L) by the density to get the mass. Neon has a density of  0.9002 g/L at STP, we can just assume it's 0.9 g/L.

That leaves the mass at 68.22 g

Then, you divide the mass by the molar mass to get the number of moles. The molar mass of neon is 20.1797 u, we can leave it at 20.18

That leaves you at approximately 3.38 moles of neon

Why metals are denser than non - metals ? ...?
Solnce55 [7]
Because their molecules are more tightly packed.                       Massdensity = ----------                     Volume
So more densely packed molecules means more mass per unit volume.  Hence metals are denser than non-metals.

Which characteristics affect ocean water’s temperature? Check all that apply. depth location mass salinity waves
RideAnS [48]

Answer:

Depth and location affect ocean water’s temperature.

Explanation:

The main source of heat for the oceans is solar radiation. That is, water is basically heated by the radiation of the Sun, which transmits energy to the surface. The ocean absorbs this energy and stores it. Seawater has high caloric capacity. This means that more energy and more time is needed to change or increase the water temperature, compared to the air temperature. Similarly, once the ocean heats up, it takes a long time for the water to completely release or lose that heat.

The temperature decreases to greater depth, because the amount of solar radiation is reduced. On the contrary, it is greater where there is greater energy or heat content.

The closer a place is to the equator, the solar energy will affect more vertically and with more intensity on it, so the warmer the temperatures will be. The further that point of the equator is found, the solar energy will reach it with a smaller angle. And if the point is near the poles, the sun's rays will arrive at a very small angle. This causes the temperature of the water of the oceans to vary depending on the earth's latitude, being higher in areas close to the equator and the tropics, and colder the closer to the poles or the further away from the temperate zones.
