Answer:

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#
