What is the density of a liquid that has a mass of 1g and a volume of 1 mL?
You could use a 1.00 mL pipette to acquire a sample of the liquid and weigh this. If you weigh 1.00 mL of liquid water it will have a mass of about 1 g so its density is about 1 g/mL or 1 g mL-1….Concept of Density.
| Pure Substance | State | Density (g mL-1) at 25°C and 1 atm |
|---|---|---|
| hydrogen | gas | 0.00008 |
How do you find the density of G and ML?
The density (d) of a material is its mass (m) divided by its volume (V). Calculate the density of an object that has a mass of 25.0g and the volume is 10.5ml. Calculate the mass of an object that has a density of 8.92 g/ml and the volume is 5.25 ml….
| vol= | 21.0g |

| 12.0g/ml |
How do you find the density of a liquid experiment?
To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.
How to calculate the density of an object?
The formula for density ( ρ – Greek lower-case letter rho) expressed in terms of the body’s volume ( v) and its mass ( m) is the equation: Solving for mass or volume requires straightforward transformations. The formula is valid for homogenous materials where the density of all points in the object equals its total mass divided by its total volume.
How is mass density different from number density?
It should be differentiated with other kinds of density e.g. number density: the particles per unit volume. Mass density is defined as the ratio of the substance’s volume to its mass.
How does the density of a substance change with temperature?
The density of a material or substance varies with its temperature and pressure, which is typically negligible for solids and liquids but is much greater for gases. Increasing the pressure on a substance decreases its volume and increases its density.
Which is the least dense substance in the world?
Some of the least dense substances (at 0.987 atm and 0.00 °C) are Hydrogen (0.0898 kg/m 3) and Helium (0.179 kg/m 3). Water is relatively dense at ~1,000 kg/m 3 while metals generally have much higher densities e.g. Iron at 7,870 kg/m 3, Gold at 19,320 kg/m 3 and Osmium at 22,570 kg/m 3.
