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
The molar mass of an element is equal to?
The element's average atomic mass.
How to find the mass of an element in a chemical compound?
To find the mass of an element in a chemical compound, you can use the atomic mass of the element from the periodic table and the number of atoms of that element in the compound. Multiply the atomic mass by the number of atoms, and you will get the mass of that element in the compound.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
How to find the mass of an element in a compound?
To find the mass of an element in a compound, you can use the formula: mass of element (mass of compound) x (percent composition of element in compound). This formula helps you calculate the mass of a specific element within a compound based on its percentage composition.
Mass number of thllium?
Thalium is a metal element. Atomic mass of it is 204.
What is the is the atomic mass of thallium?
Thallium is a meta element. Atomic mass of it is 204. Atomic number of it is 81.
What has a mass of 204?
Thallium (Tl)
How many protons are in Lead 204?
This is actually a very, very easy question to answer. Now, all atoms of the same element have the same number of protons. Otherwise, they wouldn't be the same element. For instance, if lead had one more proton, it would be bismuth, a non-toxic shiny metalloid. If it had one less, it would be thallium: a deadly poison which was only recently found. Lead has 82 protons. When the number is given by an element name (e.g. lead-204), it is also showing the atom's nucleus' mass number. Natural lead contains lead-204, lead-206, lead-207, and lead-208. Each of these contains the same number of protons, but different numbers of neutrons, hence the mass difference. To find the number of neutrons, N, we subtract the number of protons, Z, from the mass number, A. So, 204 - 82 = 122. Lead-204 contains 122 neutrons.
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
What do you call the mass of an element?
The mass of an element is known as it's ATOMIC Mass.
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
The molar mass of an element is equal to?
The element's average atomic mass.
What element creates Lead when it decays?
Thallium 204 turns into lead.

What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
What is this element atomic mass?
mass of protons + mass of neutrons present in the element (as the mass of electrons is practically negligible)
