Molar mass of N2H4 = 32 grams/mole <span>3.95 grams of N2H4 = 3.95/32 = 0.123 moles </span>
<span>This will produce 0.123 moles of N2 </span> <span>Now, From the gas law equation. </span> <span>P.V = n x R x T </span> <span>P = 1 atm (given) V = </span><span>0.123</span><span> x 0.082057 x 295 </span> <span>V = 2.97 Liters </span>
