If 8.28 x 1023 molecules of a substance have a mass of 11.61 g, what is the molar mass of the substance?
___g/mol

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

girl imma just put my comment here because i need a couple point okurrttt
