The molar mass of air is approximately 28.97 grams per mole. This value is an average based on the composition of atmospheric air, primarily nitrogen (N₂) and oxygen (O₂). How does temperature affect the mass calculation of air in a pressurized tank?
To calculate the molecular mass of methane (CH₄), we need to follow these steps:Step 1: Identify the elements in methane Methane consists of two types of atoms: carbon (C) and hydrogen (H).Step 2: Find the ato

Ammonia has a proton affinity of 207 kcal/mole, making it less likely to protonate most analytes. Proton-transfer chemical ionization is usually considered to be "soft" ionization, but the degree of the softness depends on the proton affinities of both the analyte and the reagent gas, as ...
