A stainless steel knife has a mass of 849 grams. It has a density of 7.86 g/cm³. What is the volume of the knife?

false

because it does not have the potential to be entirely used up

the correct answer would be d. hope this !

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
