A pre-1964 quarter, made predominantly of silver (density = 10.5
g/ml), was determined to have a mass of
6.25 g. What is the volume of the
quarter?

0.595 ml

Explanation:

Mass=Volume*Denisty. Substituting what we know, 6.25=V*10.5. Solving for volume, you will get 0.595 ml.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
