Calculate number of atoms from grams
WebSplitting pattern: Place the splitting pattern for the hydrogen atom. For example, if the signal has three peaks, place triplet in the target. Proton number: Place the number of protons that the group contributes to the integrated signal. For example, if the signal is created by a carbon atom with two hydrogen atoms, place two in the target.
