The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
No, oxygen does not create gravity. Gravity is a fundamental force of nature that is caused by the mass of an object. Oxygen is a gas that makes up a significant portion of Earth's atmosphere, but it does not generate gravity itself.
No. Gravity is not a substance. It is an attractive force between objects with mass.
Gravity is a constant force that acts upon objects with mass, causing them to be attracted to each other. While the strength of gravity can vary based on the mass of the objects and their distance apart, it is not considered a variable in itself.
Argon is heavier than oxygen and helium. Argon has an atomic mass of 39.948 g/mol, while oxygen has an atomic mass of 16.00 g/mol and helium has an atomic mass of 4.003 g/mol. Argon is a noble gas that is denser than both oxygen and helium.
Oxides, like rust (iron oxide), can increase the mass of iron due to the addition of oxygen atoms from the oxide molecules. This increase in mass occurs because of the combination of iron with the oxygen in the oxide.
The percentage of oxygen by mass in water is approximately 88.8%.
The percentage of oxygen (in mass) is 29,776 %.
its the percentage in mass !
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
Earth's moon is roughly 1.2% the mass of earth.
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
the percentage by mass of each element in a compound.
The molar mass of MgSO4 is 120.37 g/mol. The molar mass of oxygen is 16.00 g/mol. To find the percentage mass of oxygen in MgSO4, we divide the molar mass of oxygen by the molar mass of MgSO4 and multiply by 100 to get 47.27%.
Codeine : C18H21NO3Molecular Mass: 299Mass of oxygen present: 3 X 16 = 48Mass% of Oxygen : 48/299 * 100 = 16 %
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
Carbon makes up approximately 0.03% of Earth's atmosphere and is the fourth most abundant element by mass in the planet's crust.
