How many molecules of nitrogen dioxide are in 1.28 g of nitrogen dioxide?

In order to determine the number of molecules of nitrogen dioxide that are in 1.28 g of nitrogen dioxide, we first need to know these values:

Molar mass of nitrogen dioxide = 46.0055 g/mol
Avogadro's number = 6.022 x 10^23 molecules/mol

Then, we divide 1.28 g by the molar mass and multiply the resulting value to Avogadro's number:

1.28 g/ 46.0055 g/mol x 6.022 x 10^23 molecules/mol = 1.6755 x 10^22 molecules of nitrogen dioxide

Cordera can be warmer or colder than Hillsdale but can never be of the same temperature.

Explanation:

The reasons depend on the direction of the air current. And the position of the two cities to the equator. Because energy from the sun is transferred to Earth’s surface. Some of that energy is then transferred to the air above the surface. The closer a location is to the equator, the more energy it receives from the sun. Therefore, a location’s air temperature is affected by its distance from the equator. This is not the only cause for cooling.

Water moving from the equator is warmer than would be expected based on latitude, and so is warmer than the air it passes. Water moving from a pole is colder than would be

expected based on latitude and so is colder than the air it passes. Energy transfers from warmer substances to colder substances. Warmer air transfers energy to cooler currents and warmer currents transfer energy to cooler

air.
