Answer:see image attached

Explanation:

Kr-85 turns spontaneously into a Rubidium nucleus by emitting a beta particle and a gamma ray. The rubidium nucleus has the same mass as the krypton nucleus. The gamma rays carries off the excess energy released. It is actually a photon of light. A beta particle is actually an electron. A lot of energy is usually released in this process.

mixer [17]

Answer:

<h3>The answer is 1.99 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 16.93 g

volume = final volume of water - initial volume of water

volume = 19.7 - 11.2 = 8.5 mL

We have

density =  \frac{16.93}{8.5}  \\  = 1.9917647058...

We have the final answer as

<h3>1.99 g/mL</h3>

Hope this helps you
