Answer
4.8 x $10^{5}$ mg mg is the mass of 0.480 kg sodium hydrogen carbonate expressed in mg.
Work Step by Step
We are required to convert kg (kilogram) to mg ( milligram). Both kg and mg are units of mass in international system of unit SI.
From the SI we know that 1 kg = $10^{3}$ g
From the SI we know that 1 g = $10^{3}$ mg
So 1 kg = $10^{3}$ x $10^{3}$ mg
1 kg = $10^{6}$ mg
So to convert 0.480 kg to mg, we can write:
0.480 kg = 0.480 x $10^{6}$ mg
0.480 kg = 4.8 x $10^{5}$ mg
Thus, 4.8 x $10^{5}$ mg mg is the mass of 0.480 kg sodium hydrogen carbonate expressed in mg.
