Sa solution is made by dissolving 26.42 g of (nh4)2so4 in enough h2o to make 50.00 ml of solution. what is the molarity of the solution

Molarity is a measure of the concentration of solute in a solution

c = n ÷V
c - concentration of solute,
n - number of moles of solute
V - volume of solution

We know:

V = 50.00 mL = 0.05 L

c = ?

n = ?

Let's calculate concentration:

c = m/(V * Mr)

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
