Please help I can do Math but chemistry is kicking N2H4(l)+2H2O2(l)=N2+4H2O

Which is the limiting reactant in this reaction when 0.750 mold of N2H2 is mixed with 0.500 mold of H2O2?

Is this right 0.750 mol N2H4. Times 5N2H2O/1 mol N2 H4 = 3.75

0.500 mol H2O2. Times 5 N2H2O/2molH2O2 = 1.25

Let the ed50 of a recreational drug be defined as the amount required for 50% of a test group to feel high or get a buzz. if the ed50 value of ethanol is 470 mg/kg body mass, what dose would a 70 kg party goer need to quickly consume in order to have a 50% chance of getting a buzz? 235 mg 470 mg 32,900 mg 35,000,000 mg
