Please help 10 points and plz explain Sulfur hexafluoride is a relatively dense gas. What volume would 100 g of sulfur hexafluoride occupy at
room temperature and pressure (RTP), to 3 significant figures? The molar mass of sulfur hexafluoride is
146 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

b.

the accuracy of the data.
