Convert 2,000 g/l to the unit g/ml. 200 g/ml 200,000 g/ml 2.0 g/ml 0.002 g/ml

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

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
