The efficiency : 95%
<h3>Further explanation</h3>
Efficiency : the ratio between output and input work
In general, the value of the output of a machine is less than the value of the input because of the frictional force in the machine.
The greater the efficiency of the engine, the better the machine
Can be formulated :

w output = 190 J
W input = 200 J
The efficiency :

1170 ml is the final volume of the sample of gas, if the pressure and moles in the container is kept constant.</span>
Answer:
M = 3.69 M.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:

Which gives molar units, M, or just mol/L.
