Final answer:
To add the given quantities, convert each quantity to grams and then add them together. The answer is 3.715 grams.
Step-by-step explanation:
To add the given quantities, we need to convert them all to the same unit of measurement. Since the answer needs to be expressed in grams, we will convert each quantity to grams and then add them together.
First, we convert 0.0007 kg to grams. Since 1 kg is equal to 1000 grams, multiplying 0.0007 kg by 1000 gives us 0.7 grams.
Next, we convert 1599 mg to grams. Since 1 mg is equal to 0.001 grams, multiplying 1599 mg by 0.001 gives us 1.599 grams.
Then, we convert 1.05 g to grams. Since 1 g is equal to 1 gram, 1.05 g remains the same.
Lastly, we convert 466075 μg to grams. Since 1 μg is equal to 0.000001 grams, multiplying 466075 μg by 0.000001 gives us 0.466075 grams.
Adding all the converted quantities together, we get 0.7 grams + 1.599 grams + 1.05 grams + 0.466075 grams = 3.715075 grams.
Rounding the answer to the nearest thousandth, we get 3.715 grams.
