Question #423ae

Answer 1

I got `604muL`
(hope it is understandable)

Explanation:

Ok, let us see:
`1"dg"=1/10g=0.1g`
so
`1.45"dg"=1.45/10g=0.145g`

so your cork will have a volume:
`"density"="mass"/"volume"`
`"volume"="mass"/"density"=0.145/0.240=0.604mL`

But:

`1muL=(1"ml")/(1,000)=0.001mL`
and as a consequence:
`1mL=1/0.001muL`
so in our case we get:
`0.604/0.001=604muL`

Remember that:
`1muL=1/(1,000,000)L=0.000001L`
`1mL=1/(1,000)L=0.001L`
