Divide velocity by the wavelength.
Density = mass / volume
mass = density x volume
m = 0.917 x 2.5
m = 2.29 grams
Answer:

I don't know the answer this is really confusing but I am really sorry you have to do this.
Answer: Atomic number, atomic mass, and relative atomic mass
Explanation:
Answer: The pressure required is 0.474 atm
Explanation:
Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.
(At constant temperature and number of moles)
The equation is,

where,
= initial pressure of gas = 1.0 atm
= final pressure of gas = ?
= initial volume of gas = 
= final volume of gas =
(
Now put all the given values in the above equation, we get:


The pressure required is 0.474 atm
