Molar mass HNO₃ = 63.0 g/mol
number of moles = 3.94 / 63.0 => 0.0625 moles
Volume = moles / molarity
V = 0.0625 / 1.50
V = 0.04166 L x 1000 = 41.66 mL
hope this helps!
I think it would be penicillin as it saved many lives in its time and ours.
The the exact mass is 24.740% (according to the internet) but I’d say that it’s 25
