Gold has a density of 19.31 g/cm3. What is the mass of a sample of gold which displaces 70.8 mL of water?

1 mL and 1 cm³ are identical.

So the sample of gold displaces 70.8 cm³ of water.

Therefore the proportion in words is:

19.31 grams of gold is to 1 cm³ of gold 

             as 

X grams of gold is to 70.8 cm³ of gold

And in symbols:

19.31%2F1=X%2F70.8

Cross-multiply:

X+=+19.31%2A70.8

X+=+1367.148grams
