To determine the change in volume, you can use the ideal gas law equation: V2 = V1*(T2/T1). Substituting the values, the change in volume would be V2 - V1 = V1*(T2/T1) - V1. Just plug in the initial volume of 1.95 L, initial temperature of 250.0 K, and final temperature of 442.2 K to find the change in volume.

Why does the density of a substance not change with the sample size?

Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.


When a liquid is heated how does its volume change?

When a liquid is heated, its volume generally expands and increases, causing the molecules to move further apart. This expansion is due to the increase in the kinetic energy of the molecules, which leads to weaker intermolecular forces and greater separation between the molecules.


What solvent would you use to determine the density of magnesium nitrate?

To determine the density, you need to know the volume of a known mass of substance. To find the mass, just weigh out a sample. To determine the volume of a sample, a common method is to put some liquid in a graduated cylinder and record the volume. Then add the weighed sample (in this case MgNO3), and then record the new volume. Subtract the original volume from the new one, and the difference is the volume of the solid. To do this, accurately, the solid must be completely insoluble in the liquid. And so the liquid should not really be a solvent at all! For an ionic compound MgNO3, using a non-polar organic solvent (such as hexane) should ensure essentially zero solubility.

The volume increase.


What property like volume depends of the size of the sample?

The property that depends on the size of the sample is extensive. Extensive properties, such as mass and energy, scale with the size of the sample. This means that as the sample size increases, the value of the property also increases proportionally.

How does the volume and density of a substance change when it is heated?

When a substance is heated, its volume generally increases due to thermal expansion. On the other hand, the density of the substance usually decreases since the same amount of matter now occupies a greater volume.


How do you determine the concentration of ascorbic acid in unknown sample?

first measure the volume of the sample solution needed to change the blue color of the DCPIP solution into colourless. then, weigh the mass of the sample solution. finally calculate the concentration by using the formula: volume required t change the color of DCPIP solution (dm) per mass of the sample solution (g)

How can volume change if a substance undergoes a chemical change?

If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.

How would you determine the density of a powdered dry sample which soluble in water?

1. Apparent density: - weight a graduated cyllinder - put the sample in the graduated cyllinder up to a given volume (note this volume) - weight the graduated cyllinder with the sample - calculate the mass of the powder by difference - the density is the ratio mass of the sample/volume of the sample 2. True density of a powder: you need a helium pycnometer.
