Question

if i have 12.01 grams of carbon, i know that i have 1 mole of carbon or 6.022 × 10²³ carbon atoms. true false question 14 1 pts one mole of c₆h₆ has ____ moles of carbon and ____ moles of hydrogen present. 6, 6 1, 1 1, 2 12, 12

Explanation:

Step1: Recall molar - mass and Avogadro's number concept

The molar mass of carbon is approximately 12.01 g/mol. One mole of any substance contains Avogadro's number ($6.022\times 10^{23}$) of entities (atoms, molecules, etc.). So, 12.01 grams of carbon is 1 mole of carbon and has $6.022\times 10^{23}$ carbon atoms. The first statement is True.

Step2: Analyze the formula of $C_6H_6$

In one molecule of $C_6H_6$, there are 6 carbon atoms and 6 hydrogen atoms. So, in one mole of $C_6H_6$, there are 6 moles of carbon and 6 moles of hydrogen.

Answer:

First question: True
Question 14: A. 6, 6
