What is the percentage of oxygen in nitrous oxide?

There is one atom of oxygen per molecule of nitrous oxide (N2O). Therefore, using atomic percent, it is 1/3 oxygen.However, the mass of oxygen and nitrogen are different, and so the mass percent of oxygen is not 1/3. Nitrogen atoms weigh 14 grams/mole, and oxygen atoms weigh 16 grams per mole, so N2O weighs 44 grams per mole, so the percent oxygen is:16 ÷ 44 *100% = 36.36% by mass.


Which plants give off the most oxygen?

The plants that give off the most oxygen are typically those that are large and leafy, such as trees like oak, maple, and beech. These plants have a high rate of photosynthesis, which allows them to produce more oxygen as a byproduct.

Which plants give oxygen all the time?

Why do plants give out carbon dioxide in the dark and oxygen in the light and can this reduce oxygen in the bedroom at night?

Plants release carbon dioxide during respiration, which occurs both day and night. In the presence of sunlight, plants undergo photosynthesis, where they absorb carbon dioxide and release oxygen. The amount of oxygen released during photosynthesis is usually more than the carbon dioxide released during respiration, so there should not be a significant reduction in oxygen levels in a bedroom at night due to plants.

Yes, they will give you a large dose of magnesium which works as a muscle relaxer to stop your labor, then they will give you a smaller continuous dose to prevent you from going back into labor. I was 30 weeks pregnant, 3cm dilated and 80% effaced and they were very successful in stopping my labor.
