Answer:

D. 18.7 grams

Explanation:

The coefficients are the key.

Create a proportion with them, and the molar mass, and then solve for x:

\frac{2}{3}  =  \frac{x}{28}  \\ 3x = 2(28) \\ 3x = 56 \\ x = 18.666... = 18.7

If you have a 200.0 gram sample of carbon, how many moles of carbon do you have? A. 200.0 B. 17.0 C. 16.66 D. 12.01
lukranit [14]

Answer:

B. 17.0.

Explanation:

Hello!

In this case, considering that based on the atomic mass of the carbon atom, which means that 1 mole of carbon weights 12.01 grams, we can set up the following proportional factor to compute the moles of carbon in 200.0 grams:

200.0gC*\frac{1molC}{12.01gC}\\\\17.0molC

Thus, the answer would be B. 17.0.

Best regards!
