Question

How many mg does a 643 kg sample contain?

Answer 1

`6.43x19^8mg`

Step-by-step explanation:

Hello,

In this case, this unit conversion is performed by knowing that 1 kg of mass contains 1000 g and 1 g contains 1000 mg, therefore, the result is:

`643kg*(1000g)/(1kg) *(1000mg)/(1g)\\ \\=6.43x10^8mg`

Regards.
