Answer:
<h3>The answer is 10 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 300 g
volume = final volume of water - initial volume of water
volume = 40 - 10 = 30 mL
We have

We have the final answer as
<h3>10 g/mL</h3>
Hope this helps you
(B), because 1.0 moles would be 6.02 x 10^23 molecules. So you have half a mole.<span>

By the lloks ofit you cant see it send a better picture
Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction
