What element makes up about 75 percent of the sun's mass?
Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
Why there is 75 percent of the atmosphere's mass in the troposphere?
The majority of Earth's atmosphere mass is found in the troposphere because this is where air molecules are most densely packed due to the gravitational pull. As altitude increases, air pressure decreases, leading to a thinning of the atmosphere. The troposphere is the lowest layer of the atmosphere and contains various gases like nitrogen, oxygen, and water vapor that together make up 75 percent of the atmosphere's total mass.
How much mass of air does the Troposphere contain?
{75-80}
What percent of the sun is hydrogen?
About 74% of the Sun's mass is hydrogen. This element is essential for nuclear fusion reactions that power the Sun, converting hydrogen into helium and releasing energy in the process.
Why is 75 percent of the atmosphere's mass found in the troposphere?
The majority of the atmosphere's mass is concentrated in the troposphere because this is the layer closest to Earth's surface where air is most dense and pressure is highest. As you move higher up in the atmosphere, the air becomes less dense and pressure decreases, leading to a decrease in mass as well.
Which gas makes up most of the suns mass?
About 75% of the Sun's mass is Hydrogen, 23% is Helium and the remaining 2% consists of heavier elements such as carbon and oxygen.
What element makes up about 75 percent of the sun's mass?
Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
Water makes up what percent of the earth?
75%
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
What makes up 75 percent of earth surface?
Oceans
What are the two elements that make up 75 percent of the total mass of the crustal rocks of the earth?
Oxygen and silicon are the two elements that make up 75 percent of the total mass of the crustal rocks on Earth.
What is the percent of 75 percent?
The percent of 75% is 75%.
What Makes up 75 percent of the air and is found in the 15th group?
Nitrogen.
Does the sun accounts for 75 percent or 99 percent of all the matter in the solar system?
In fact, the Sun accounts for over 99.8% . Most of the rest is contained in Jupiter.
What is the weight percent of a caffeine solution made by dissolving 8.35 g of caffeine C8H10N4O2 in 75 g of benzene C6H6?
The weight percent of a caffeine solution made by dissolving 8.35 g of caffeine in 75 g of benzene is calculated as: Weight percent = (mass of caffeine / total mass of solution) * 100 Weight percent = (8.35 g / (8.35 g + 75 g)) * 100 Weight percent ≈ 10.0%
If 75 percent of the isotopes of an element have a mass of 35.0 amu and 25 percent of the isotopes have a mass of 37.0amu what is the atomic mass of the element?
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
Why is 75 percent of the atmosphere mass found in the troposphere?
Gravity. It tends to pull air downward.
