Answer:
1.25×10¯² Kg
Step-by-step explanation:
From the question given above, the following data were obtained:
Mass (in grams) = 12.5 g
Mass (in kilograms) =..?
Thus, we can obtain the mass of the sample in kilogram (kg) by doing the following:
Recall:
1000 g = 1 kg
Therefore,
12.5 g = 12.5 g × 1 kg/ 1000 g
12.5 g = 0.0125 Kg = 1.25×10¯² Kg
From the above illustration, 12.5 g is equivalent to 1.25×10¯² Kg.
Therefore, the mass of the sample in kilogram is 1.25×10¯² Kg
