Answer:
0.000144gcm⁻³
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 = [tex]\frac{mass}{volume}[/tex] = [tex]\frac{0.36}{2500}[/tex]
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.
