Answer: The mass of pentane is 108 grams.
Explanation:
To calculate the mass for the given number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
We are given:
Moles of pentane = 1.50 moles
Molar mass of pentane = 72.15 g/mol
Putting values in above equation, we get:
[tex]1.50mol=\frac{\text{Mass of pentane}}{72.15g/mol}\\\\\text{Mass of pentane}=(1.50mol\times 72.15g/mol)=108g[/tex]
Hence, the mass of pentane is 108 grams.
