Final answer:
To convert the mass of a 5.00-grain aspirin tablet to milligrams, convert grains to ounces, ounces to grams, and grams to milligrams. A 5.00-grain aspirin tablet is approximately 324.56 milligrams.
Step-by-step explanation:
The question is asking to convert the mass of a 5.00-grain aspirin tablet into milligrams. Since 1 grain is equal to 0.00229 ounces, we first need to convert ounces to grams and then to milligrams. We know that there are 28.3495 grams in an ounce, and 1 gram is equal to 1000 milligrams.
First, convert 5.00 grains to ounces:
5.00 grains * 0.00229 oz/grain = 0.01145 oz
Next, convert 0.01145 ounces to grams:
0.01145 oz * 28.3495 g/oz = 0.324555675 grams
Lastly, convert grams to milligrams:
0.324555675 g * 1000 mg/g = 324.555675 mg
Therefore, a 5.00-grain aspirin tablet is approximately 324.56 milligrams.
