Answer 2

Calculation of Maximum Daily Mass of Paracetamol for an Adult

To calculate the maximum daily mass of paracetamol for an adult, we need to convert the given maximum daily dose in moles to grams.

The molar mass of paracetamol (C8H9NO2) is calculated as follows: - Carbon (C) has a molar mass of 12.01 g/mol. - Hydrogen (H) has a molar mass of 1.01 g/mol. - Nitrogen (N) has a molar mass of 14.01 g/mol. - Oxygen (O) has a molar mass of 16.00 g/mol.

Using these values, we can calculate the molar mass of paracetamol as follows:

(8 * 12.01 g/mol) + (9 * 1.01 g/mol) + (1 * 14.01 g/mol) + (2 * 16.00 g/mol) = 151.17 g/mol.

Given that the maximum daily dose of paracetamol for an adult is 0.0241 moles, we can calculate the maximum daily mass as follows:

0.0241 moles * 151.17 g/mol = 3.648 g.

Therefore, the maximum daily mass of paracetamol for an adult is 3.648 grams.

Calculation of Maximum Number of Tablets an Adult Can Take in a Day

To calculate the maximum number of tablets an adult can take in a day without exceeding the maximum daily dose of paracetamol, we need to divide the maximum daily mass of paracetamol by the mass of each tablet.

Given that the mass of each tablet is 500 mg (0.5 g), we can calculate the maximum number of tablets as follows:

3.648 g / 0.5 g = 7.296.

Since we cannot take a fraction of a tablet, the maximum number of tablets an adult can take in a day without exceeding the maximum daily dose of paracetamol is 7 tablets.

Please note that it is important to always follow the instructions provided by a healthcare professional or the medication's packaging when taking any medication.
