Answer:
Density = 0.32g/mL
Step-by-step explanation:
Density of a substance can be calculated using the formula:
Density (g/mL) = mass (g)/volume (mL)
According to the information provided in this question, mass of the substance = 80grams, volume = 250cm³/mL
Note that, the pressure and temperature are not needed to calculate the density of the substance.
Density = 80/250
Density = 0.32g/mL
