A mineral is a naturally occurring chemical compound,
usually of crystalline form and abiogenic in origin. A mineral has one specific
chemical composition. Coal is not a mineral because it is organic while a
mineral is inorganic that have repeating crystalline structure.

Answer: The pressure in torr is 461 torr
Explanation:
To calculate the relation of density and molar mass of a compound, we use the ideal gas equation:
PV=nRT
P = pressure
V = Volume
n = number of moles
R = gas constant = 0.0821 Latm/Kmol
T = temperature =
Number of moles (n) can be written as:
where, m = given mass
M = molar mass = 44 g/mol
where,
where d = density = 2.54 g/L
The relation becomes:
PM=dRT
(760torr=1atm)
Thus the pressure in torr is 461 torr
