Answer: The volume of the balloon up there is 6.192 L.
Explanation:
Given: = 1.80 L,
= 785 mm Hg (mm Hg = 0.00131579) = 1.032 atm
= 0.300 atm,
= ?
Formula used to calculate volume is as follows.
Substitute the value into above formula as follows.
Thus, we can conclude that the volume of the balloon up there is 6.192 L.
Answer:
The resulting solution contains approximately 666 g of water.
Explanation:
In the initial solution we have:
1g salt : 8g sugar : 200g water
This means that the ratios are:
In the final solution we have:
5g salt: xg sugar: yg water
The new ratios are:
Now we can calculate the amount of sugar in the final solution:
Finally, we calculate the amount of water:
The answer for the following problem is mentioned below.
Explanation:
Given:
Initial pressure () = 290 kPa
Final pressure () = 104 kPa
Initial volume () = 18.9 ml
To find:
Final volume ()
We know;
From the ideal gas equation;
P × V = n × R × T
where;
P represents the pressure of the gas
V represents the volume of gas
n represents the no of the moles
R represents the universal gas constant
T represents the temperature of the gas
So;
P × V = constant
P ∝
From the above equation;
represents the initial pressure of the gas
represents the final pressure of the gas
represents the initial volume of the gas
represents the final volume of the gas
Substituting the values of the above equation;
=
= 52.7 ml
<u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
