Answer:
the mass number is the number of protons and neutrons added and the average atomic mass is the weight of the protons and neutrons
Answer:
The energy of an electron in many–electron atom is determined by both principal quantum number (n) and azimuthal quantum number (l)
Answer:
a) The volume is 5.236x10⁻¹³L
b) The molarity of a single virus is 1.91x10¹² mol/L
c) The molarity for a 100 virus particles is 1.91x10¹⁴ mol/L
Explanation:
a) Given:
D = diameter of the cell = 10 μm
r = radius = 10/2 = 5 μm
The volume of the spherical cell is equal:
If 1 μm³ = 1x10⁻¹⁵L, then 523.6 μm³ = 5.236x10⁻¹³L
b) The molarity is:
For a single virus within the cell
c) For a 100 virus particles the molarity is:
The correct match are as follows:
Boyles Law is about a gas at constant temperature. Therefore, the correct match would be the volume of a gas varies inversely with pressure if the temperature is kept constant.
Charles Law would be that the volume of a gas varies directly with temperature if the pressure is kept constant.
Gay-lussac's law would be that the pressure of a gas varies directly with temperature if the volume is kept constant.
