Question
12. (8 pts) In your reaction, ONE molecule (mole) of the reactant makes ONE molecule (mole) of the product. However, this is not always the case. Shown below is a reaction where TWO molecules (moles) of the reactant form ONE molecule (mole) of the product. This changes the chemical yield calculation somewhat. 2 reactant product Imagine that you performed the reaction above, and that you started with exactly 2 g of the reactant and you formed 1.5 g of the product. a. (1 pt.) What is the molecular formula of the reactant? b. (1 pt.) What is the molecular weight of the reactant?Explanation / Answer
from the reaction
a) molecular formula of the reactant = C5H6
b) molecular weight of the reactant = 12*5+1*6 = 66 g/mol
