WebAug 15, 2024 · The molecular ion is often given the symbol M + or M ⋅ + - the dot in this second version represents the fact that somewhere in the ion there will be a single unpaired electron. That's one half of what was originally a pair of electrons - the other half is the electron which was removed in the ionization process. WebSep 21, 2024 · Step 2: Solve. n = P V R T = 0.987 atm × 0.677 L 0.08206 L ⋅ atm/K ⋅ mol × 296 K = 0.0275 mol. Now divide g by mol to get the molar mass. molar mass = 1.211 g 0.0275 mol = 44.0 g/mol. Since N has a molar mass of 14 g/mol and O has a molar mass of 16 g/mol, the formula N 2 O would produce the correct molar mass.

WebApr 18, 2024 · You can calculate AR by dividing your total revenue (TR) by your quantity sold: AR = TR/Q. Marginal Revenue vs. MR = ΔTR / ΔQ. AR = TR/Q. MR = ΔTR (1,045 – 1,000) / ΔQ (11 – 10) = 45. MR = ΔTR (1,080 – 1,045) / ΔQ (12 – 11) = 35. TR = P x Q. TR (500) = P (10) x Q (50) MR = ΔTR (549.45 – 500) / ΔQ (55 – 50) = 9.89.
