Question

Sealed 2500 flask is full to capacity with 0.36 g of a substance. Determine density of the substance. Guess if the substance is a gas liquid or solid.

Answer 1

The density of the substance can be calculated by dividing its mass by its volume. To determine if the substance is a gas, liquid, or solid, we can consider its density in comparison to the densities of known substances. Density = Mass / Volume = 0.36 g / 2500 mL, it is likely a solid.

Step-by-step explanation:

The density of a substance can be calculated by dividing its mass by its volume. In this case, the mass of the substance is 0.36 g, and the volume of the flask is 2500 mL. To calculate the density, we divide the mass by the volume:

Density = Mass / Volume = 0.36 g / 2500 mL.

To determine if the substance is a gas, liquid, or solid, we can consider its density in comparison to the densities of known substances. If the substance has a low density, it is likely a gas. If it has a moderate density, it is likely a liquid. And if it has a high density, it is likely a solid.

Answer 2

0.000144gcm⁻³

Step-by-step explanation:

Given parameters:

Volume of flask = 2500mL

Mass of substance = 0.36g

Solution:

Density is the mass per unit volume of a substance. The flask used to determine the density of the substance will have a volume of 2500mL if equal amount of water is added to it.

Now, we must convert the given volume to that which would be more convenient to work with.

Density can be expressed as gcm⁻³ or kgm⁻³.

We have to convert the given volume to cubic centimeters.

1mL = 1cm³

The volume of the flask in cubic centimeters is 2500cm³.

Density =
`(mass)/(volume)` =
`(0.36)/(2500)`

Density of the substance = 0.000144gcm⁻³

The substance is probably a gas. The density of water is 1gcm⁻³. Any value far below this should be a gas. Our answer is a very low density value.
