how many atoms of argon gas are in 137 ml container at the pressure in the container is 8.80 X 10^5 mmhg and the temperature to 794 K
Answer:
#Ar atoms = 1.47 x 10²²
Explanation:
PV = nRT => n = PV/RT
P = 8.80 X 10⁵ mmHg = 8.80 X 10⁵ mmHg/760mmHg·atm⁻¹ = 11.58atm
V = 137ml = 0.137 Liter
n = ? moles Ar = ? moles Ar x 6.02 x 10²³ Atoms Ar/mole Ar
R = 0.08206 L·atm/mol·K
T = 794K
PV = nRT => n = PV/RT = 11.58atm·0.137L / 0.08206L·atm/mol·K·794K
=> n = 0.0243mole Ar = 0.0244mole Ar x 6.02 x 10²³ atoms Ar/mole Ar
= 1.47 x 10²² atoms Ar

which one of these in not a principle of cell theory
Answer:
The correct answer is D) Only cells containing mitochondria can reproduce.
Explanation:
Cell theory mainly states that every organism present on this earth are made up of cell and the cell is the basic and smallest unit from which life is made up of. It also states that all the new cell that comes into existence are evolved from the old(pre-existing) cells.
Therefore any cell that contain or do not contain mitochondria can reproduce because new cells come from an old cell not from mitochondria, for example, a bacterial cell does not have mitochondria but they reproduce by binary fission.
Therefore any cell which is living can reproduce so the principle which is not currently understood is D) Only cells containing mitochondria can reproduce.
