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.
