Answer:
m = 673 g
Explanation:
We need to find the mass of 5.90 mol of [tex]C_8H_{18}[/tex]
Molar mass of [tex]C_8H_{18}[/tex] is:
[tex]M=8\times 12+1\times 18\\\\=114\ g/mol[/tex]
Let m be the mass of 5.90 mol of [tex]C_8H_{18}[/tex]. Using mole concept to find it.
No of moles = mass/molar mass
[tex]m=5.9\times 114\\\\=672.6\ g\\\\\approx 673\ g[/tex]
So, the required mass is 673 g. Hence, the correct option is (d).
