Ответ:
8.90 is the correct answer
Ответ:
density = mass / volume
density = 222.50 g / 25 ml
density = 8.9 g/ml
therefore, the correct answer would be the third option. the density of the unknown metal would be 8.9 grams per milliliter. it would have a high density as expected since it is a metal and it would occupy a small space but would have a heavy mass.
Ответ:
The vapor pressure of a liquid is the pressure of the vapor produced by evaporation of a liquid or solid above the liquid or solid in a closed container. The hydrogen bonding between liquid water molecules explains why water has an unusually low vapor pressure.
