Identify the conversion factor between milligrams (mg) and grams (g). Since 1 gram equals 1000 milligrams, the conversion factor is \(1\,\text{g} = 1000\,\text{mg}\).
Set up the conversion by dividing the given mass in milligrams by 1000 to convert it to grams: \(\text{mass in grams} = \frac{\text{mass in milligrams}}{1000}\).
Substitute the given value into the equation: \(\text{mass in grams} = \frac{16822\,\text{mg}}{1000}\).
Perform the division to find the mass in grams (do not calculate the final number here, just set up the expression).
Interpret the result to select the correct answer from the options provided, ensuring the units are consistent and the decimal point is correctly placed.
