Answer:
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. ... Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.
If this satisfies you please consider giving me brainliest :)
Find solubility
- Mass of solute/Mass of solvent×100
- 50/100×100
- 50%
So half amount of solute is dissolved .
Hence the solution is saturated
Answer:
Molecular mass, 
Explanation:
Given that,
Mass of gas, m = 0.46 g
Volume of the container, V = 515 cm^3
Pressure, P = 153 kPa
Temperature, T = 322 K
We need to find the molecular mass of this gas. We know that,
PV =nRT
n = no of moles

No of moles = mass/molecular mass
Let molecular mass is M

So, the molecular mass of this gas is
