Answer 1

Answer on Question #77111 – Chemistry – Other

Task:

Benzene, $C_6H_6$ is a potent carcinogen. How many grams are in 0.250 mole sample of benzene?

Solution:

Molar mass of benzene = $M(C_6H_6) = 6 * \text{Ar}(C) + 6 * \text{Ar}(H)$;

$$M(C_6H_6) = 6 * 12 + 6 * 1 = 78 \frac{g}{mol}$$

Use the compound's molar mass:

$$0.25 \, \text{mol} * \frac{78 \, g}{\text{mol}} = 19.5 \, g \text{ of benzene}$$

Answer: 19.5 grams are in 0.250 mole sample of benzene
