Convert 5.43 x 10-6 Mm to cm dimensional analysis
plz i need help i have more if someone can help me

Explanation:

1mm = 1/10 cm

5.43 x 10^-6 mm = 5.43 × 10^-7 cm

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
