The density of this material is 2 g/cm^3.There are 24 cm^3.
What is the total mass?

Explanation:

Mass can be found by multiplying the density by the volume.

The density is 2 grams per cubic centimeter.

The volume is 24 cubic centimeter.

Substitute the values into the formula.

Multiply. Note that the cubic centimeters, or cm³ will cancel each other out.

The mass of the material is 48 grams.

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.

the dissolution of polymer can be thermodynamically described in 2 steps.
