Calculate the density of gold (in units of g/mL) if a 5.00 cm cube has a mass of 2.41kg

Turn 2.41 kg into grams :

2.41 * 1000 => 2,410 g

1 cm³ = 1 mL , so:

5.00 cm³ = 5.00 mL

Therefore:

D = mass / volume

D = 2,410 / 5.00

D = 482 g/mL

The volume of a 5cm cube is 0.5dm*0.5dm*0.5dm = 0.125dm^3
1dm^3 = 1l
So 0.125dm^3 = 125mL
This gives us 2410/125 = 19.28
So the density of gold is 19.28g/mL
Final check: Gold is indeed 19.3g/mL

In terms of the atmosphere, which of the following best describes the oxygen that is present?
Viktor [21]
The atmosphere is considered homogeneous. It isn’t exactly on the smallest scales but that doesn’t matter. Homogenous means the composition will be the same in any sample taken from the substance. And clearly, the atmosphere is mostly gas. So the last answer is right

All of the following equations are statements of the ideal gas law except
evablogger [386]

Answer:

  • The first equation, <em>a. PV = nRT</em>, <u>is not</u> <em>a valid statement of the ideal gas law.</em>

Explanation:

The basic expression for the<em> ideal gas law</em> is:

  • pV=nRT      .......... [Equation 1]

Where:

  • n is the number of moles of the gas
  • V is the volume occupied by the gas
  • p is the pressure exerted by the gas molecules
  • T is the temperature in absolute scale (Kelvin)
  • R is the Universal gas constant (0.0821 atm-liter /K-mol or the equivalents in other units)

You can perform different algebraic operations to obtain equivalent equations:

<u>Choice b) Divide equation 1 by T and you get</u>:

  • pV / T = nR, which is the choice b. from your list.

<u>Choice c) Divide equation 1 by n × V and you get</u>:

  • p/n = RT / V, which is the choice c. from your list.

<u>Choice d) Divide equation 1  n × T and you get</u>:

  • pV / (nT) = R, which is the choice d. from your list.

The choice a. p = nRTV states that p and V are in direct relation, when the ideal gas law states that p and V are inversely related, so that equation is wrong.

<u>Conclusion: </u>the choice a, p = nRTV, is not a statement of the ideal gas law.
