Explanation:

The density of an object can be found by using the formula

From the question

Density = 15.29 g/mL

mass = 309.109 g

To find the volume make volume the subject and solve for the volume

That's

We have

volume = 20.216415

We have the final answer as

Volume = 20.22 cm³ to two decimal places

Hope this helps you

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
