On a given day in San Francisco, the relative humidity is 50%. This means that the actual amount of water vapor in the air is the amount of water vapor needed for saturation. Group of answer choices

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
