Question

How many molecules are in 3.8 grams of c6h6

Answer 1

Answer:

i dont really know how to explain but its the math

Explanation:

296.8249919999934

Answer 2

Answer:

Molar mass of benzene [C6H6] = (12 × 6) + (6 × 1)

= 78 grams

from avogadro's number:

$78 \: g \: of \: benzene = 6.02 \times {10}^{23} \: molecules \\ 3.8 \: g = \{ \frac{3.8 \times (6.02 \times {10}^{23}) }{78} \} \\ \\ = { \boxed{ \boxed{2.93 \times {10}^{22} \: molecules}}}$
