Question
How many $\mathrm{mEq}$ of $\mathrm{K}^{+}$are represented in a $500-\mathrm{mg}$ tablet of potassium phenoxymethyl penicillin (molecular weight $=388 \mathrm{~g} / \mathrm{mol}$; valence $=1$ )?
Step 1
Given that the tablet weighs 500 mg and the molecular weight of potassium phenoxymethyl penicillin is 388 g/mol, we can calculate the number of moles using the formula: Number of moles = Mass / Molecular weight Number of moles = 500 mg / 388 g/mol = 0.00129 mol Show more…
