Determine the volume of fluid in the graduated cylinder shown.
2 answers:
Answer:
47.3 ml
Explanation:
The graduated cylinder is shown in the image attached.
Now we have to take a good look at the cylinder, the lines between 45 and 50 are 46, 47, 48 and 49. Even though the points in between two lines weren't graduated but we can intelligently guess the correct volume by observing the upper meniscus of the liquid. Hence the answer.

Answer : The pressure of hydrogen gas is 8.96 atm.
Explanation :
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 2 moles of Al react to give 3 moles of gas
So, 4.50 moles of Al react to give moles of
gas
Now we have to calculate the moles of gas when percent yield is 75.4.
Now we have to calculate the pressure of gas.
Using ideal gas equation :
PV = nRT
where,
P = Pressure of hydrogen gas = ?
V = Volume of the hydrogen gas = 14.0 L
n = number of moles of hydrogen gas = 5.09 moles
R = Gas constant =
T = Temperature of hydrogen gas = 300 K
Putting values in above equation, we get:
Therefore, the pressure of hydrogen gas is 8.96 atm.

According to the Charles' Law, the volume of a gas is proportional to temperature when pressure is constant. When going from New York to Florida, if the pressure is left constant the volume of the tires will increase.
The final volume of the tires can be calculated from the following equation, derived from Charles' Law:
