Answer:
33.5 g/mol
Explanation:
PV=nRT
(1.40 atm)(8.00 L)=n(0.08206)(295 K)
n=0.463 mol
15.50 g/0.463 mol=33.5 g/mol
Pure water is alkaline = 7 , acid rain is slightly acidic = 4
Reactant is the left side. 4+3=7
1740 g because the molar mass is 133.33g/mol, mulitplied by 11.37 mol = 1743.36. 1740 is closest and it may be a bit off depending on how many sig figs are used for the molar mass. So 1740g
