Answer:
0.46875g/ml
Explanation:
Density(p) = m / v unit - g/ml or Kg/m^3
Given
mass = 2.4g
volume = 5.12ml
p = m / v
= 2.4g / 5.12ml
= 0.46875g/ml
Answer:
See explanation
Explanation:
If the energy of the ground state E1 is known, then we need to measure the difference in energy between the energy levels E5 .and E1. We can obtain this by measuring the frequency or wavelength of a photon that is emitted when an electron moves from energy level E5 to E1.
From Bohr's model;
ΔE = E5 - E1
Hence;
E5 = ΔE + E1
Answer: Water displacement
Explanation:
When you put an irregularly shaped object in a graduated cylinder, the water level rises. Subtract the original number of ml from the number of ml it was displaced, and you get its volume.
