Answer:
42.0g/mol
Explanation:
The steps for this question is to use the ideal gas law, and then use n=m/M to find molar mass.
PV = nRT
n= PV/RT
Change 23 degrees to 296.15 K and 684mmHg to kpa
n = (91.1925kpa)(2.00L)/(8.314Lkpa/mol K)(296.15K)
n= 0.074mol
n = m/M
M = m/n
M = 41.98489g/mol
2Na(g) + Cl2(g) 2NaCl(s) is the redox reaction. Na atoms lose electrons and Cl atoms gain electrons, thereby getting oxidized and reduced respectively and fulfilling the requirement of a redox reaction.
