What is the atomic mass of an element if one hatom has a mass of 2.107 x 10x10 to the -22 power g
I wonder if you made a typo?
If the mass is 2.107E-22, then that time Avogadro's number (6.022E23) will get the molar mass. Or use 2.107 x 10 x 10^-22 if you didn't make a typo.
To find the atomic mass of an element, we need to determine the mass of one atom. In this case, we are given that one atom has a mass of 2.107 x 10^-22 g.
The atomic mass of an element is usually expressed in atomic mass units (amu). To convert the given mass into amu, we need to use the Avogadro's number (6.022 x 10^23 atoms/mol).
1 amu is defined as 1/12 the mass of a carbon-12 atom, which is approximately equal to 1.66054 x 10^-24 g.
Now, let's calculate the atomic mass of the element:
(2.107 x 10^-22 g) / (1.66054 x 10^-24 g/atom) = 1.27 x 10^2 atoms
So, the atomic mass of the element is approximately 1.27 x 10^2 amu.
To find the atomic mass of an element, we need to know the number of atoms and their individual masses. In this case, you have provided the mass of a single atom.
To determine the atomic mass, we can use Avogadro's number, which states that one mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, or ions). We can calculate the atomic mass using the following formula:
Atomic mass = (Mass of one atom) x (Avogadro's number)
Given:
Mass of one atom = 2.107 x 10^-22 g
Using Avogadro's number:
6.022 x 10^23 atoms/mol
Now we can calculate the atomic mass:
Atomic mass = (2.107 x 10^-22 g) x (6.022 x 10^23 atoms/mol)
To simplify the calculation, let's express the mass in scientific notation:
2.107 x 10^-22 = 2.107E-22
Atomic mass = (2.107E-22 g) x (6.022 x 10^23 atoms/mol)
Now, multiply the numbers together:
Atomic mass = 12.68 g/mol
Therefore, the atomic mass of the element is approximately 12.68 grams per mole (g/mol).
