How many total atoms are in 0.500 g of p2o5?

1.49 x 10^22 atoms
 
First determine the molar mass of P2O5 Atomic mass of Phosphorus = 30.973762 Atomic mass of Oxygen = 15.999 Molar mass of P2O5 = 2 * 30.973762 + 5 * 15.999 = 141.9425 Now determine how many moles of P2O5 you have 0.500 / 141.9425 = 0.003523 Since there's a total of 7 atoms per molecule of P2O5, multiply the number of moles by 7 to get the number of moles of atoms you have. 7 * 0.003523 = 0.024661 Finally, multiply by avogadro's number (6.0221409 x 10^23) to get the total number of atoms. 0.024661 * 6.0221409 x 10^23 = 1.48512 x 10^22

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
