What element makes up seventy five percent of the suns mass?
Hydrogen.
How do you calculate the percent by mass of an element in a compound?
To calculate the percent by mass of an element in a compound, you divide the mass of the element by the total mass of the compound and then multiply by 100. This gives you the percentage of the compound's mass that is made up of that specific element.
What is the mass percent composition of an element in a compound?
The mass percent composition of an element in a compound is the percentage of the total mass of the compound that comes from that specific element. It is calculated by dividing the mass of the element by the total mass of the compound and multiplying by 100.
Percent composition is expressed as a percent by?
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
Does The element with the largest subscript in a formula have the largest percent by mass in the compound?
Sometimes, but not necessarily: The largest percent by mass in a compound is that of the element for which the product of the subscript and the atomic weight is highest. For example, there is more carbon than hydrogen by mass in CH4.
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
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.
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is the percent compistion of a compound?
The percent composition of a compound tells the amount of each element in the compound as a percentage. It is possible to find if the mass of an element and the total mass of the compound is known.
What does the mass percent of an element tell you about molecule?
it tells you how much of the molecule the element is
What does mass percent of an element tell you about a molecule?
it tells you how much of the molecule the element is
What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
