Worked Solution & Example Answer:A journalist studied the data in Table 2 - AQA - A-Level Biology - Question 4 - 2020 - Paper 1
Step 1
Maximum dose of aspirin
Answer
The maximum dose of aspirin is 0.6 g every 4 hours, which amounts to:
- Daily dosage calculation:
egin{align*} ext{Number of doses per day} &= 24 / 4 = 6 \ ext{Total daily dose} &= 0.6 imes 6 = 3.6 ext{ g} \ ext{Sodium content in one tablet} &= 0.15 ext{ g} \ ext{Total sodium from maximum dose} &= 0.15 imes 6 = 0.9 ext{ g} \ ext{Results} & : 0.9 ext{ g} < 2.4 ext{ g} (RDA)\ ext{Conclusion} &: ext{False for aspirin.}
\end{align*}
Step 2
Maximum dose of paracetamol
Answer
The maximum dose of paracetamol is 1.0 g every 6 hours, which amounts to:
- Daily dosage calculation:
egin{align*} ext{Number of doses per day} &= 24 / 6 = 4 \ ext{Total daily dose} &= 1.0 imes 4 = 4.0 ext{ g} \ ext{Sodium content in one tablet} &= 0.43 ext{ g} \ ext{Total sodium from maximum dose} &= 0.43 imes 4 = 1.72 ext{ g} \ ext{Results} & : 1.72 ext{ g} < 2.4 ext{ g} (RDA)\ ext{Conclusion} &: ext{False for paracetamol.} \end{align*}
