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.

How many grams of phosphorus are in 500 grams of calcium phosphide?
To find the grams of phosphorus in calcium phosphide, first find the molar mass of calcium phosphide (Ca3P2 = 3Ca + 2P = 340.08 + 230.97 = 276.42 g/mol), then calculate the mass percent of phosphorus in calcium phosphide (2P/276.42 g/mol * 100%). Finally, determine the grams of phosphorus in 500 grams of calcium phosphide by multiplying the mass percent by 500 grams.
What is the percent composition by mass of phosphorous in ammonium phosphate?
Ammonium phosphate ((NH4)3PO4) contains one phosphorus atom in the formula. To calculate the percent composition by mass of phosphorus, you need to find the molar mass of phosphorus and the molar mass of the entire compound. Then, divide the molar mass of phosphorus by the molar mass of the compound and multiply by 100 to get the percentage.

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 grams are in the 1.204 1020 atoms of phosphorus used to coat your television screen?
To calculate the grams of phosphorus, you need to know the molar mass of phosphorus and then use Avogadro's number to convert from atoms to grams. The molar mass of phosphorus is approximately 30.97 g/mol. Therefore, you can calculate the grams of phosphorus using this information.
Can you calculate the mass of a single copper atom?
