(a) 43.6 mg; (b) 520 mg
(a) <em>Mass of phosphoric acid (PA) in a dose
</em>
Mass of PA = 2 tsp × (21.8 mg PA/1 tsp) = 43.6 mg PA
(b) <em>Mass of PA in the bottle
</em>
<em>Step 1</em>. Convert <em>ounces to millilitres
</em>
Volume = 4 oz × (30 mL/1 oz) = 120 mL
<em>Step 2.</em> Calculate the mass of PA
Mass of PA = 120 mL × (21.8 mg PA/5 mL) ≈ 520 mg PA

I’m not too sure but try this: focal point
Recall that a mole is defined as Avogadro's number of particles what the formula of caffeine basically tells us is that every molecule of caffeine you will have 8 atoms of carbon 10 atoms of hydrogen 4 atoms of nitrogen and 2 atoms of oxygen so if we have 0.3 moles of caffeine we will have 4*0.3 moles of nitrogen which is 0.12 and you got the idea
The percentage error that would be introduced in a 35.0 mL sample of liquid is 2.86%
<h3>Data obatined from the question</h3>
From the question given, the following data were obtained:
- Absolute error = 1 mL
- True measurement = 35 mL
- Perecentage error =?
<h3>How to determine the percentage error</h3>
The percentage error that would be introduced can be obtained as illustrated below:
Percentage error = (Absolute error / True measurement) × 100
Percentage error = (1 / 35) × 100
Percentage error = 2.86%
Thus, percentage error that would be introduced is 2.86%
