Answer:
I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.
Density = mass / volume
1.5 = m / 50.0
m = 1.5 x 50.0
m = 75 g

Answer:
Explanation:
When group 7 elements react , their atoms gains one electron into their highest occupied energy level ( outer shell) to form single negative - charged ion .
As you move down the group , the outer shells get increased i.e an additional electron shell is added thereby increasing the atomic radius of the atom. The electrons in the outer shell move further away from the nucleus as we go down the group .
Therefore the force of attraction between the shells and nucleus is decreased .
This makes attracting an extra electron difficult . And so ability of the atom to attract electron to fill the outermost shell reduces which means the reactiveness of the atom reduces.

Answer:
+ 3
Ex planation:
Al3+ indicates an ion of aluminum having a charge of + 3. I.e., since an aluminum atom normally has 13 protons and 13 electrons, this ion has 10 electrons (-10 charge) and 13 protons (+ 13 charge) giving it a charge of + 3 (-10 + 13 = +3).
