huh that's suspicious that's weird
The density of the liquid at the given temperature is 1.622 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
<h3>How to determine the density </h3>
The density of the liquid can be obtained as illustrated below:
- Mass of liquid = 40.55 g
- Volume of liquid = 25 mL
- Density of liquid =?
Density = mass / volume
Density = 40.55 / 25
Density of liquid = 1.622 g/mL

The boiling point of oxygen is higher than nitrogen's boiling
The reason the boiling point of O2 is higher is not because of increased van der Waals interactions, but simple physics. The mass of a molecule of O2 is greater than that of a molecule of N2, so the molecule of O2 traveling at a speed sufficient to break out of the liquid phase has a greater kinetic energy than an analogous N2 molecule.
The net effect is that more energy must be distributed throughout a sample of O2 to achieve a given vapor pressure (in this case equal to atmospheric pressure) than for a sample of N2. More energy means greater temperature.
C. Decomposition
Since one reactant turns (decomposes) into two products, it is a decomposition reaction
