PLEASE HELP JUST PLS. I NEED HELP ON THIS ASAP. ITS DUE TOMORROW AT SCHOOL AT 8:30AM. I NEED THE WORK AND THE ANSWER I need the work and the answers. Pls :(((

Idid the calculation and i get 875,000,000 which can be written as 8.75 x 10^6?

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

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
