Explanation:
Answer:
The molar mass of the organic solid is 120.16 g/mol.
The molecular formula of an organic solid is
Explanation:
Let the molecular mass of an organic solid be
where,
=Elevation in boiling point =
Mass of organic solid= 0.561 g
Mass of diphenyl = 24.9 g = 0.0249 kg (1 kg = 1000 g)
= boiling point constant = 8.00 °C/m
m = molality
Now put all the given values in this formula, we get
Percentage of carbon in an organic solid = 40.0%
x = 4.0
Percentage of hydrogen in an organic solid = 6.7%
y = 8.0
Percentage of hydrogen in an organic solid = 6.7%
y = 4.0
The molecular formula of an organic solid is
Answer:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
