find the mass of 3.49 moles of gold. use the formula( n=M/m; where m id mass, n is mlles and M is molar mass).

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

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
