Which solutions have a density greater than 1.0 g/mL?
Mass = 888 g Volume = 800 mL
Mass = 7.8 g Volume = 8.7 ml
Mass = 725 g Volume = 715 mL
Mass = 1.3 g Volume = 1.1 ml
Mass = 18 g Volume = 19 mL
Mass = 1.25 g Volume = 1.78 ml

Respuesta :

Density = Mass / Volume

A) Density = 888/800 = 1.11g/mL > 1.0g/mL
B) Density = 7.8 / 8.7 = 0.897g/mL < 1.0g/mL
C) density = 725 / 715 = 1.01 g/mL > 1.0g/mL
D)density = 1.3/1.1= 1.18 g/mL > than 1.0 g/mL
E) Density = 18/19 = 0.95g/mL < 1.0g/mL
F) Density = 1.25/1.78 = 0.7 g/mL < 1.0g/mL

SUMMARY:
A C D have densities greater than 1.0g/mL

The solutions that have their mass greater than their volumes are:

  • Mass = 888 g Volume = 800 mL  
  • Mass = 725 g Volume = 715 mL
  • Mass = 1.3 g Volume = 1.1 ml

The ratio of the mass of a substance to its volume is known as the density of the substance. Mathematically;

Density = Mass/Volume

For any solution to have a density greater than 1, the mass of the substance must be greater than its volume.

For the given option, the solutions that have their mass greater than their volumes are:

  • Mass = 888 g Volume = 800 mL  
  • Mass = 725 g Volume = 715 mL
  • Mass = 1.3 g Volume = 1.1 ml
