The molar mass of sucrose is measured to be 342.3 g. The value of Avogadro's number, correct to six significant digits, is 6.022
Nimfa-mama [501]
<span>Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:

0.24 g (1 mol / 342.3 g) ( 6.022 x 10^23 molecules /  1 mol ) =4.222 x 10^20 molecules

What is the molecular formula of a compound that molecular mass of 54 g/mol and an empirical formula of C₂H₃? C₂H₃, C₄H₆, C₆H₉,
Shkiper50 [21]

Answer:

Molecular formula = C₄H₆

Explanation:

Given data:

Molecular mass of compound = 54 g/mol

Empirical formula = C₂H₃

Molecular formula = ?

Solution:

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = 12×2 + 3×1 = 27 g/mol

n = 54 / 27

n = 2

Molecular formula = n (empirical formula)

Molecular  formula = 2(C₂H₃)

Molecular formula = C₄H₆
