How can you find the mass from the number of atoms?
protons plus the number of neutrons.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
What does an elements atomic mass tell about the atoms that make up that element?
It tells you the mass of how many protons and how many neutrons plus the tiny mass of the electrons. The electrons are about .0016 amu so they still have mass
What contributes to an atoms atomic number and to its mass number?
The atomic number is the number of protons in the atom (this can never change). The mass number is the number of protons plus the number of neutrons, this varies because atoms lose neutrons so they take one mole (6.0223x10^23) of the atoms, and average it.
What is a mass number atomic mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The Atomic Mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
What is the mass of 4.771E plus 22 atoms of neodymium?
4.771 X 1022 atoms neodymium (1 mole Nd/6.022 X 1023)(144.2 grams/1 mole Nd) = 11.42 grams of neodymium --------------------------------------
Does 2HCI plus Mg equal 2Mg atoms?
Does 2HCI plus Mg equal 2Mg atoms
What is conserved in the reaction shown below. N g plus 3F g 2NF g?
Mass is conserved in any chemical reaction. If the reaction is balanced it will show that mass is conserved. In others words the mass of the reactants will equal the mass of the products...just to add the balanced reaction should be (i didn't know if you forgot the subscripts or not): N2 + 3F2 --> 2NF3 so is it atoms only mass only mass and atoms only or moles only
What is the percent of carbon in C2H12O6?
The formula given shows that each molecule of the substance contains two atoms of carbon, twelve atoms of hydrogen, and six atoms of oxygen. Therefore, the gram molecular mass of the substance is twice the gram atomic mass of carbon plus 12 times the gram atomic mass of hydrogen plus six times the gram atomic mass of oxygen. In numerical terms, this is [2(12.011) + 12(1.00794) + 6(15.9994)] or 132.11. (Only five significant digits are justified, because only five digits are given for the atomic mass of carbon.). Therefore the mass fraction of carbon in the substance is 24.022/132.11 or 0.18183. Multiplying by 100 yields 18.183 % of carbon in the substance.
