8 0

Answer:

Number of atoms in 52g of He is 7.829X10^24.

Explanation:

Solution,

Given,

No of mole of atoms (NA) = 6.023x10^24.

Mass ogiven helium=52g

Atomic mass of helium=4

Lets do sep by step,

1) No. of atom in 52g of He.

= NAxmass/At.mass

= 6.023X10^23x52/4

= 7.829 x 10^24.

The amount of water vapor in a given volume of air is ______________ .The amount of water vapor in the air at any one time depen
Eduardwww [97]

Answer:

The amount of water vapor in a given volume of air is humidity.The amount of water vapor in the air at any one time depends on temperature . Warmer air holds more water than cooler air. Clouds form when humidity is low and thetemperature is high . Relative humidity is defined as the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface. Dew is related to the humidity of the previous day. The air temperature at which water vapor in the air condenses onto cool surfaces is the dew point.

What would be the volume in liters of 640g of oil if the density of the oil is 0.8g/mL
Alexus [3.1K]

Hey there!

Mass = 640 g

Density = 0.8 g/mL

Volume = ?

Therefore:

D = m / V

0.8 = 640 / V

V = 640 / 0.8

V = 800 mL

hope that helps!
