Answer:
2.61 L
Explanation:
p1v1 = p2v2
p1v1 / p2 = v2

Explanation:
When light is shined on certain metals, electrons may be knocked off the metal. This is called the photoelectric effect. By assuming that light is quantized, Einstein was able to explain the photoelectric effect. ... When UV light of a long wavelength and low frequency is shined on the zinc nothing happens.
The Atomic number of an element depends upon how many protons and nuetrons are in the element.To find the atomic mass you need to add the protons and nuetrons together
