Answer:
(a)
(b)
(c)
Explanation:
Hello,
(a) In this case, with the given formula we easily compute the mass of gold contained in the sovereign as shown below:
(b) Now, by knowing the density of gold and copper, 19.32 and 8.94 g/cm³ respectively, we compute each volume, by also knowing that the rest of the coin contains copper:
(c) Finally, the volume is computed by dividing the total mass over the total volume containing both gold and copper:
Best regards.
The mass of the copper cylinder is 177065.856g
Given:
Radius of the copper cylinder R=12cm
Height of the copper cylinder H=44cm
Density of the cylinder=8.90
To find:
Mass of the copper cylinder
<u>Step by Step by explanation:</u>
Solution:
According to the formula, Mass can be calculated as
and from this
Where, m=mass of the cylinder
=density of the cylinder
v=volume of the cylinder
And also cylinder is provided with radius and height value.
So volume of the cylinder is calculated as
Where =3.14
r=radius of the cylinder=12cm
h=height of the cylinder=44cm
Thus,
v=3.14 \times 144 \times 44
And we know that,
Substitute the known values in the above equation we get
m=177065.856g or 177.065kg
Result:
Thus the mass of the copper cylinder is 177065.856g
Answer:
the concentration of PCl5 in the equilibrium mixture = 296.20M
Explanation:
The concept of equilibrium constant was applied where the equilibrium constant is the ration of the concentration of the product over the concentration of the reactants raised to the power of their coefficients. it can be in terms of concentration in M or in terms of Pressure in atm.
The detaied steps is as shown in the attached file.
