Answer 2

Answer : The mass in kilograms of 100 pills is 0.078 kg.

Explanation :

First we have to convert the mass of one pill from 'mg' to 'kg'.

conversion used :

`1mg=10^(-6)kg`

So,
`780mg=(780mg)/(1mg)* 10^(-6)kg=780* 10^(-6)kg`

Now we have to calculate the mass for 100 pills.

As, 1 pills has mass =
`780* 10^(-6)kg`

So, 100 pills has mass =
`100* 780* 10^(-6)kg`

= 0.078 kg

Therefore, the mass in kilograms of 100 pills is 0.078 kg.
