If an unknown liquid has a density of 0.756 g/mL and a mass of 2.00 g, what is its volume?

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question

mass = 2 g

density = 0.756 g/mL

So we have

We have the final answer as

Hope this helps you

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
