Rutherford postulated the existence of some neutral particle having mass similar to proton but there was no direct experimental evidence. Several theories and experimental observations eventually led the discovery of neutron.
Molar mass
Ca₃(PO₄)₂ = 310 g/mol
1 mole -------------------> 310 g
2.3x10⁻⁴ mole ---------> ?
m = 2.3x10⁻⁴ * 310 / 1
m = 0.0713 g
hope this helps!

Biochemical sediment like black shale (carbonaceous shale) and lignite and coal will form from the weathering ie reduction and decomposition of plant organic matter and thus store it in the geosphere, Also, carbon is naturally sequestered in the formation of carbonate rocks like limestone by combination of the carbon dioxide in the oceans (which may be in the form of carbonic acid) with metals to form calcium and magnesium carbonate compounds.
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 =
