Answer:
0.779 mol
Explanation:
Since the gas is in a bottle, the volume of the gas is constant. Assuming the temperature remains constant as well, then the gas pressure is proportional to the number of moles:
so we can write
where
p1 = 730 mm Hg = 0.96 atm is the initial pressure
n1 = 0.650 mol is the initial number of moles
p2 = 1.15 atm is the final pressure
n2 is the final number of moles
Solving for n2,
To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.
By Newton's second law we understand that,
F = ma
Where,
m = mass
a = acceleration (at this case the gravity acceleration)
In the case of density, we know that it is described as the proportion of mass versus volume, that is,
Where,
m = mass
V = Volume
The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,
Mass can be expressed as,
Therefore the tension in cable AB is 6103.94N
