Isomers are compound having same molecular formula but different structure formula
The molecular formula of butanoic acid and ethyl acetate is C4H8O2.
The structure formula of butanoic acid is CH3CH2CH2COOH, while structural formula of ethyl acetate is CH3COOCH2CH3.
Thus, both butanoic acid and ethyl acetate have same number of constituent atoms, therefore they have same atomic mass. Thus, molecular mass of ethyl acetate is 88.1 amu.
To solve for the new water level, let us first calculate
for the volume of the copper cylinder. The formula we can use is:
V = m / ρ
where V is the volume, m is the mass of the copper and ρ
is the density, therefore:
V = 48.85 g / (8.96 g / cm^3)
V = 5.45 cm^3
since cm^3 = mL
V = 5.45 mL
The new water level will be the initial volume of the
graduated cylinder plus the volume of the copper cylinder, therefore:
new water level = 20 mL + 5.45 mL
new water level = 25.45 mL
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.
