The density of gold is 19.3 g/cm3 and the density of lead is 11.4 g/cm3. If you have 5 grams of gold and 5 grams of lead, which will have the greater volume?

Given :

The density of gold is and the density of lead is respectively .

To Find :

Which have greater volume .

Solution :

We know , density is given by :

Now , volume of 5 gm gold .

Also , volume of 5 gm lead .

Therefore , volume of lead will be greater than gold.

Hence , this is the required solution .

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.
