Answer:
The boiling point is directly proportional to the surface area which is proportional to the molecular weight.
Explanation:
A compound is a substance that consists of 2 or more elements chemically combined in a fixed proportion.
Compounds can be broken down ijt0 simple substances by chemical means but, elements cannot.
The density is 4 g/cm³ or 4000 kg/m³.
Density = mass/volume = 12 g/3 cm³ = 4 g/cm³
The measurement of 4 g/cm³ is already in <em>SI units</em>.
In SI <em>bas</em>e units,
Density = (4 g/1 cm³) × (1 kg/1000 g) × (100 cm/1 m)³ = 4000 kg/m³
Answer:
if what you need is the final answer
the final answer is = 0.228 and I think the unit is Liter(L).
Explanation:
Density = mass/volume
Since at STP, one mole of any gas occupies 22.4 liters, therefore, the volume is equal.
So, we will arrange based on mass.
From the periodic table:
mass of carbon = 12 grams
mass of calcium = 40 grams
mass of chlorine = 35.5 grams
mass of copper = 63.5 grams
Based on this:
copper has the highest density.
