What mass of He contains the same number of atoms as 5.0 g Kr?
To find the mass of He containing the same number of atoms as 5.0 g Kr, we need to use the fact that atoms are indivisible entities. First, determine the number of atoms in 5.0 g Kr using the molar mass of Kr. Then, calculate the mass of He containing the same number of atoms by dividing the atomic mass of He by Avogadro's number and scaling it up to match the number of Kr atoms.
What mass of copper contains the same number of atoms as 68.7 g of iron?
To find the mass of copper containing the same number of atoms as 68.7 g of iron, we need to first calculate the number of atoms in 68.7 g of iron using its molar mass. Then, we convert this number of atoms to copper atoms using the ratio of their molar masses. Finally, we determine the mass of copper corresponding to this number of atoms.
Why do chemical equations have the same number of atoms on each side?
Chemical equations follow the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. As a result, the number of atoms on each side of the equation must be the same to maintain the balance of mass.
What is the difference between two atoms of carbon having the same number of neutrons?
The difference would lie in their atomic mass. The number of neutrons in an atom affects its atomic mass, which is the sum of the protons and neutrons in the nucleus. Therefore, two atoms of carbon with the same number of neutrons would have the same atomic mass.
How many atoms of hydrogen appear on each side of the equation?
To determine the number of hydrogen atoms on each side of the equation, you would need to balance the equation first. Once the equation is balanced, count the number of hydrogen atoms on both the reactant and product sides to compare. The number of hydrogen atoms should be the same on both sides of the balanced equation.
When 2 atoms appear to have same atomic mass?
When they are of the same element.

What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

What are atoms with the same atomic number but different mass called?
Atoms with the same atomic number are all atoms of the same element. However, if the atoms have different molecular weights, they are isotopes of the same element.
Do atoms of the same number have a different mass number?
Atoms of the same atomic number (= number of protons in each nucleus) can have different mass numbers because of containing different numbers of neutrons in each atom.
Why are the mass of the products the same during the magnesium and hydrochloric acid reaction?
Mg + 2HCl --> MgCl2 + H2 Count the atoms on the left and then count the atoms on the right. You will see the exact number of atoms and this exact number of atoms will have the same mass.
What describes atoms with the same number of protons and different number of neutrons?
Isotopes describe atoms with the same number of protons and different number of neutrons. These isotopes have the same atomic number but different mass numbers, resulting in variations in atomic mass.
What are atoms that have the same number of protons but different mass number?
Atoms with the same number of protons but different mass numbers are called isotopes. Isotopes have the same atomic number but different atomic weights due to variations in the number of neutrons in the nucleus.
Do isotopes have the same atomic number and different mass numbers?
Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
What is the same as the atomic mass number of an element?
Atoms atomic number represents their number of protons.
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What are atoms that have different masses but the number of protons?
Atoms that have different masses but the same number of protons are called isotopes. Isotopes of an element have the same number of protons, which determines the element's identity, but a different number of neutrons, leading to variations in atomic mass.
