What volume does .0685 mol of gas occupy at STP? 1mole =22.4
2 answers:
Answer : The volume of gas at STP is, 1.53 liter
Solution : Given,
Moles of a gas = 0.0685 mole
As we know that at STP,
1 mole of gas contains 22.4 liter volume of gas
As, 1 mole of gas contains 22.4 liter volume of gas
So, 0.0685 mole of gas contains volume of gas
Therefore, the volume of gas at STP is, 1.53 liter

Answer:
The pair of arrows which represents the relationship of speeds of the two cars is;
The second option as shown in the attached drawing
Explanation:
The given parameters are;
The reading on the speedometer of one car = 20 m/s
The reading on the speedometer of the other car = 72 km/h = 20 m/s
The blue arrow = 20 m/s
Therefore, given that the speeds of both cars are equal (20 m/s = 72 km/h = 20 m/s), the pair of arrows that represent the relationship of speeds of the two cars is two equal length blue arrows which is the second option
The attached diagram showing the pair of arrows that represents the relationship of speeds of the two cars is drawn using Microsoft Visio.
Answer:
The percentage deviation is %
Explanation:
From the question we are told that
The concentration is of the solution is
The true absorbance A = 0.7526
The percentage of transmittance due to stray light %
Generally Absorbance is mathematically represented as
Where T is the percentage of true transmittance
Substituting value
%
The Apparent absorbance is mathematically represented
Substituting values
= 0.7385
The percentage by which apparent absorbance deviates from known absorbance is mathematically evaluated as
%
Since Absorbance varies directly with concentration the percentage deviation of the apparent concentration from know concentration is
%
