The molar mass of oxygen atoms has to be chosen from the given options, given that the
Concept Introduction:
Sum of atomic masses of all the atoms that are represented in chemical formula of substance is known as formula mass. If atomic mass and chemical formula of a compound is known, then formula mass can be calculated.
Molar mass is the mass that is expressed in grams of a substance that is equal to the formula mass of the substance numerically. Molar mass of an element is unique for the particular element. Two natural elements can never have the same molar mass.
Mole is defined as the amount of substance that has as many elementary particles as there are atoms in exactly 12 grams of C126.
The relationship between the atomic mass unit and grams unit is,
6.02 x 1023 amu=1.00 gor1 amu=1.66 x 10−24 g

- The SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
