Some one help me please I'm stuck Show using two conversion factors how you would convert from 0.020 kg into mg.

julia-pushkina [17]

Answer:

$=2.0x10^4mg$

Explanation:

Hello there!

In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:

$=0.020kg*\frac{1000g}{1kg} *\frac{1000mg}{1g} \\\\=2.0x10^4mg$

Best regards!
