(a)
Interpretation:
The molar masses of molecules are given by using chemical formula to be calculated.
Concept introduction:
Molar mass is also known as molecular weight, which is the sum of the total mass in grams of all the atoms that present in a particular molecule. If we know the formula of a compound then we can easily determine the compound’s molar mass. We know that a formula consists of atoms and it is important to count atoms carefully, especially in compounds with polyatomic ions enclosed in parentheses.

- For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ? Will the first MgBr product that forms in this reaction create a new CC bond? olo ? OH جمله O Yes Ⓒ No MgCl ? Will the first product that forms in this reaction create a new CC bond?
