If a substance has a relatively low melting point (below 400ºF), then it is either molecular polar or molecular non-polar

If a substance has a high melting point, then it is either metallic, covalent network, or ionic

The stronger a substance’s bonds, the higher its melting point

Answer:

The detailed calculation is shown in the attached file.

last condition (1000 K in 150.000 dm3) will have the least deviations and it is the condition where real gas will behave as ideal gases

Explanation:

Real gas behave more ideally or they tend towards ideality when there is the least deviation, or their inter-molecular forces between their molecules are mainly responsible for their deviations as such gases with the strongest intermolecular forces shows the strongest deviations. As such, when their is an increase in temperature and volume and a decrease in pressure, real gas tends towards ideal gas in this case.

From the three conditions given, it is obvious that the last condition(1000 K in 150.000 dm3) will have the least deviations.

Molar mass of carbon

Taya2010 [7]

Answer: 12.011g/mol

Explanation: The molar mass of any element is usually stated at the bottom of periodic table (depending of your table anyways). Remember that the periodic table speaks to you in moles so every molar mass under the element is for 1 mole. By this I mean for example, 1 mole of Carbon = 12.011g of Carbon.
