1. Find the molar mass of Novocain:
* C: 12.01 g/mol * 13 = 156.13 g/mol
* H: 1.01 g/mol * 21 = 21.21 g/mol
* N: 14.01 g/mol * 2 = 28.02 g/mol
* O: 16.00 g/mol * 2 = 32.00 g/mol
* Cl: 35.45 g/mol * 1 = 35.45 g/mol
Total molar mass = 156.13 + 21.21 + 28.02 + 32.00 + 35.45 = 272.81 g/mol
2. Calculate the moles of Novocain:
* moles = mass / molar mass
* moles = 1.574 g / 272.81 g/mol
* moles = 0.00577 mol
3. Determine the moles of carbon atoms:
* Since there are 13 carbon atoms in each molecule of Novocain, multiply the moles of Novocain by 13:
* moles of carbon = 0.00577 mol * 13
* moles of carbon = 0.0750 mol
Therefore, there are approximately 0.0750 moles of carbon atoms in 1.574 g of Novocain.
