What is the density of a gas at STP that has a molar mass of 50.0 g/mol? Student A wrote some preliminary notes: PV = nRT; n = m/M; and d = m/V

known: unknown

T = 273 K d = g/cm3

P = 1 atm

R = 0.08125 atm

M = 50.0 g/mol

n = 1 mol

If PV = nRT and n = m/M, then, density = PM/RT

What is the density of the gas?

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

do you need the explaination?

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
