603.040 has 5 significant figures in it I'm pretty sure
Answer:
Units of a = 
Units of b = 
Explanation:
The Van der Waal's equation is:-
Where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value
a and b are van der Waal's constant
If pressure is taken in atm and volume in L. So,
represents the pressure correction term. Then,
Units of a =
represents the volume correction term. Then,
Units of b =
The nucleus!! This is made up of protons and neutrons that each weigh about 1 amu.
Electrons are not found in the nucleus and weigh almost nothing so chemistry in school doesn’t bother with them :)
The density is calculated with the following formula:
density = mass / volume
If there is water on the pan of scale, you will read the mass of the mineral plus mass of water.
Using this value to calculate the density (ignoring the fact that you had water) you will obtain a higher density of the mineral than the real one.
