Answer:
12 g
Explanation:
We want to prepare 1 L of a 0.15 M NaOH solution. The moles of NaOH required are:
0.15 mol/L × 1 L = 0.15 mol
The molar mass of NaOH is 40.00 g/mol. The mass corresponding to 0.15 mol is:
0.15 mol × (40.00 g/mol) = 6.0 g
The starting solution is 50% by weight. The mass of solution that contains 6.0 g of NaOH is:
6.0 g NaOH × (100 g solution/50 g NaOH) = 12 g solution

Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
Answer
Accordingly the order of electronegativity of the given elements would be: Fluorine > Chlorine > Bromine > Iodine. ( Fluorine has the highest electronegativity.)
