Molarity = moles / liter
a) M = 2/4 = 0.5 M
b) Moles = 4/(30 + 16 + 1)
= 0.085
M = 0.085 / 2 = 0.0425 M
c) Moles = 5.85 / (23 + 35.5)
= 0.1
M = 0.1 / 0.4
= 0.25 M
This easy bro there is only one answer Gravity
but here my advance word
Sometimes the gravity of big objects would capture smaller ones in orbit. This could be one way the planet acquired the moon
We know that density = mass /volume
so
mass=volume*density
volume=mass/density
so c is wrong
Answer: Aufbau principle
Explanation: Aufbau Principle suggests that in filling electrons into orbitals, lower energy orbitals must be filled before higher energy orbitals.
Answer:
they all have the same amount of kinetic energy
