Which of the following is the correct formula to calculate percent by mass? (5 points) O [Mass of solution (g) = mass of solute (9)] x 100
O [Mass of solute (9) = mass of solution (9)] < 100
[Mass of solute (g) - mass of solution (9)] x 100
O [Mass of solution (g) + mass of solute (9)] x 100

well, they made a movie about how animals lived there.

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.
