Mass conversion: A sample fo platinum has a mass of `0.432 mg`. What is its mass in kilogram?
Strategy: Consturct the required unit factors using the relationship `1g = 1000 mg` and `1 kg = 1000 g` and follow the sequence
`mg rarr g rarr kg`

Text Solution

Verified by Experts

`? kg = (0.432 mg) xx ((1g)/(1000 mg)) xx ((1kg)/(1000g))`
`= 0.432xx10^(-6) kg`
`= 4.32xx10^(-7) kg`
