What is percent by mass over volume?
Percent by mass over volume is a measurement that expresses the mass of a substance in a given volume as a percentage. It is calculated by dividing the mass of the substance by the volume of the solution and then multiplying by 100. This measurement is commonly used in chemistry to quantify the concentration of a solute in a solution.
Why nitrogen is 98 percent in environment as oxygen is 21 percent?
Nitrogen is more abundant in the environment (78% in air) compared to oxygen (21% in air) because nitrogen is relatively inert and doesn't easily react with other elements, allowing it to accumulate over time. This is in contrast to oxygen, which is more reactive and often participates in chemical reactions, leading to varying concentrations in the atmosphere.
