The concentration of HCl is equal to 2.54mol/L.
<h3>Mole calculation</h3>
To solve this question, one must use the molarity calculation, which corresponds to the following expression:
Thus, to find the molarity of the sample, the following calculations must be performed:
So, 0.00254 moles were added per 10ml, so we can do:
So, the concentration of HCl is equal to 2.54mol/L.

<u>Answer:</u> The fugacity coefficient of a gaseous species is 1.25
<u>Explanation:</u>
Fugacity coefficient is defined as the ratio of fugacity and the partial pressure of the gas. It is expressed as
Mathematically,
Partial pressure of the gas is expressed as:
Putting this expression is above equation, we get:
where,
= fugacity coefficient of the gas
= fugacity of the gas = 25 psia
= mole fraction of the gas = 0.4
P = total pressure = 50 psia
Putting values in above equation, we get:
Hence, the fugacity coefficient of a gaseous species is 1.25
The answer should be Pure substance
Answer:
Precentage error = 7.23%
Explanation:
The precentage error formula is the useful method for determining precision of your experimental result
It can be calculated using :
So we get percentage error = 7.23%
Precision means how close the experimental value to the true value or theoretical value
If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment
If the percentage error is zero it means the experiment is perfectly done without inaccuracy
