1.27g

Explanation:

Given parameters:

Number of moles of C₂₀H₄₂ = 4.52 x 10⁻³moles

Unknown:

Mass of the compound = ?

Solution:

The mole is a comfortable unit for measuring chemical substances.

  number of moles = \frac{mass}{molar mass}

 Molar mass of  C₂₀H₄₂  = (12 x 20) + (1 x 42) = 240 + 42 = 282‬g/mol

Mass of the compound = number of moles x  molar mass

                                       = 4.52 x 10⁻³ x 282

                                         = 1.27g
