Let's assume ideal gas behavior for simplicity. We could use the equation below:
PV=nRT
Solve for n or the number of moles.
n = PV/RT = (3×10⁻³ atm)(1 L)/(0.0821 L·atm/mol·K)(250 K)
n = 1.462×10⁻⁴ moles ozone
For every 1 mole of any substance, Avogadro stipulated that there is an equivalent of 6.022×10²³ molecules. Thus,
# of ozone molecules = 1.462×10⁻⁴ mol * 6.022×10²³ molecules/1 mol
<em># of ozone molecules = 8.8×10¹⁹</em>
Answer: two moles
Explanation:
In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt. of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75molesFe2O3 there are 1.75×2 moles or 1.75×56 gm of iron
The average kinetic energy of an ideal gas is calculated as
KE_avg = 3/2 kT
where T is the temperature in Kelvin and k=R/N_A; R is the universal gas constant and N_A is the number of moles.
Thus, upon substitution we get
KE_avg = 3/2(8.314/1)(100+273)
KE_avg = 3/2(8.314)(373)
KE_avg = 4651.683
The average kinetic energy of 1 mole of a gas at 100 degree Celsius is 4651.683 J.
Hi,
The option above that is correct to the question is 'Honey'.
Gold, steel, and water are all organic or natural resources.
