Answer for screen readers
The molar mass of the compound C14H10 is $178.22 \text{ g/mol}$.
Steps to Solve
-
Identify Atomic Masses First, we need to find the atomic masses of the elements in the compound. For carbon (C), the atomic mass is approximately 12.01 g/mol, and for hydrogen (H), it is approximately 1.008 g/mol.
-
Count the Number of Atoms In the molecular formula C14H10, there are 14 carbon atoms and 10 hydrogen atoms.
-
Calculate Total Mass of Each Element Now, multiply the number of atoms by the atomic mass for each element.
- For carbon: $$ 14 \text{ atoms} \times 12.01 \text{ g/mol} = 168.14 \text{ g/mol} $$
- For hydrogen: $$ 10 \text{ atoms} \times 1.008 \text{ g/mol} = 10.08 \text{ g/mol} $$
- Add the Masses Together Now add the total masses of carbon and hydrogen to find the molar mass of the compound: $$ \text{Molar mass} = 168.14 \text{ g/mol} + 10.08 \text{ g/mol} = 178.22 \text{ g/mol} $$
The molar mass of the compound C14H10 is $178.22 \text{ g/mol}$.
