Ответ:
1. PV = nRT. and solving for n (moles F2) we have
n = PV/RT = (1.50 atm)(15.0 L)/(0.0821 Latm/Kmol)(280K)
n = 0.9788 moles F2
mass NaCl = 0.9788 mol F2 x 2 mol NaCl x 58.4 g/mol = answer
Explanation:To find mass NaCl at STP just substitute 1 atm for pressure and 273K for temperature in the above equation and follow the rest of the calculations above.
