A sealed apparatus that can expand contains a cylindrical reservoir completely filled with water. The apparatus is heated until all the water boils, and the steam then occupies the measured volume shown in the table.
| quantity | value |
|---|---|
| radius of reservoir | 2.00 cm |
| depth of reservoir | 4.00 cm |
| density of water | 1000 kg/m3 |
| volume occupied by steam | 0.0840 m3 |
Calculate the density of the steam.
