Final answer:
To calculate the glucose dose, convert moles to mass using the molar mass of glucose, then convert that mass to ng if required, ensuring accurate dosing by considering significant figures and prescribed dosage.
Step-by-step explanation:
Calculating Glucose Dose
To calculate the dose of glucose for therapy, you need to know the mass of glucose required. The process involves converting moles of glucose to the desired mass. If you have 0.310 moles of glucose, you would use the molar mass of glucose, which is approximately 180.1559 g/mol, to find the mass in grams.
Once you have the mass in grams, if you need to convert it to nanograms (ng), you use the conversion factor that 1 gram = 1,000,000,000 ng. To ensure accurate dosage, consider the precise molar mass and the required conversion factors. Remember to verify the result against the prescribed glucose therapy dosage.
For an example, a calculation for 0.310 moles of glucose would be:
- (0.310 moles) × (180.1559 g/mol) = mass in grams
- Mass in grams × (1,000,000,000 ng/g) = dose in ng
Always think about your result to ensure it aligns with the desired therapeutic outcomes and has the correct significant figures.
