How do I calculate injected mass?

Question

The protocol is the following:

Rat#1 - 2mCi at high specific activity

Rat#2 - 2mCi at low specific activity

I need calculate the injected mass into each rat. I'm a bit confused because I don't have exact specific activity values at this point.

I was also given this additional information:

Molar mass of hot compound = 275g/mol

Specific Activity units = mCi/umol

So where do I go from here? I believe that dose = mCi, and that it may be the missing link??

Can anyone help? Thanks
