Your closes answer would be a.10
Molar mass CH4 = 16.0 g/mol
* number of moles:
932.3 / 16 => 58.26875 moles
T = 136.2 K
V = 0.560 L
P = ?
R = 0.082
Use the clapeyron equation:
P x V = n x R x T
P x 0.560 = 58.26875 x 0.082 x 136.2
P x 0.560 = 650.76
P = 650.76 / 0.560
P = 1162.07 atm
The iron nail displaces the Cu from the copper sulfate solution. This results in the color of CuSO4's disappearance. Copper is less reactive than iron.
Answer:
<h2>The answer is 35 mL</h2>
Explanation:
Density of a substance can be found by using the formula

From the question we are finding the amount of space the gas will occupy that's the volume of the gas
Making volume the subject we have

From the question
mass = 23.8 g/mL
Density = 0.68 g/mL
Substitute the values into the above formula and solve
That's

We have the final answer as
<h3>35 mL</h3>
Hope this helps you
Answer:
