The only stable isotope of phosphorus is phosphorus-31. This means that the mass number of a phosphorus atom is 31 amu. The formula for converting amu into grams is: 1 Atomic Mass unit = 1.66053886 x 10-24 grams. So, to convert 31 amu to grams, do the following calculation:
31 amu x (1.66053886 x 10-24 g/1 amu) = 5.1 x 10-23 g*
*The answer is rounded to two significant figures because when multiplying or dividing, you round the answer to the fewest number of significant figures used in the calculation, which in this case is 31 with only two sig figs.

What is the mass of one atom of chlorine?
35.5 grams per mole or 5.90*10^-23 for a single atom
How many moles in 2.3 grams of phosphorus?
mole = mass/molar mass mass=2.3 grams molar mass=30.97 2.3/30.97=0.0742 moles
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
When radioactive phosphorus decay it emits a positron will the resulting nucleus be another isotope of phosphorus?
No, whenever an atom emits a positron its atomic number is decreases by one unit (because a proton is converted into a neutron and a positron) but atomic mass remains the same so phosphorus is converted into silicon atom with same atomic mass.
When an atom of phosphorus becomes a phosphide ion P-3 the radius increaed Why?
it increases because it takes on more mass to grow
What is the average mass of a single silicon atom in grams?
The average mass of a single silicon atom in grams is the ratio 28,085/6,022140857.10e23.
What is the mass in grams of a single atom of each of Ne?
mother earth
What is the mass of one atom of chlorine?
35.5 grams per mole or 5.90*10^-23 for a single atom
What atom has an atomic mass of 31?
Phosphorus
What is the mass of a single copper atom is 1.055 x10-22 grams This is the same mass as?
1.055 × 10-25 kg.
What is the mass of one atom of phosphorus?
Phosphorus is a non meta element. Atomic Mass of it is 31. Atomic number of it is 15.
What is mass in grams of a single atom of bromine?
The molar mass of bromine is approximately 79.9 grams/mol. Since one mole of any substance contains Avogadro's number of particles (6.022 x 10^23), the mass of a single bromine atom is approximately 79.9 grams/mol divided by 6.022 x 10^23, which is approximately 1.33 x 10^-22 grams.
What is the mass of a single argon atom in grams?
Since Argon has a relative atomic mass of 39.95, and mols = grams / RAM, one could calculate 39.95 / (6.02*10^23) = 6.63 * 10^-23 grams [0.00000000000000000000006634g] for a single argon atom, where 6.022 * 10^23 is roughly Avogadro's constant (the count of atoms in a mole). IF my math is correct.
How many moles in 2.3 grams of phosphorus?
mole = mass/molar mass mass=2.3 grams molar mass=30.97 2.3/30.97=0.0742 moles
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
What is the mass in grams of a boron atom?
11
How do you calculate a mole of an atoms weight in grams?
you take the atomic mass of the atom (or molecule) and you have the mass in grams
