Answer:
1.1 M
General Formulas and Concepts:
- Molarity = moles of solute / liters of solution
Explanation:
<u>Step 1: Define variables</u>
1.2 mol KCL
1.1 L of solution
M = unknown
<u>Step 2: Solve for Molarity</u>
- Substitute: M = 1.2 mol/1.1 L
- Evaluate: M = 1.09091
<u>Step 3: Check</u>
<em>We are given 2 sig figs. Follow sig fig rules.</em>
1.09091 M ≈ 1.1 M
it is 6,6-Dibromoheptan-2-ol

Moles of the sucrose in the reaction is given by mass of sucrose divided by relative formula mass of sucrose,(mass/R.F.M)
R.F.M of sucrose is therefore (12 x12)+(1 x22) +(16 x11) =343
number of moles=10g/342=0.029moles (answer A)
