What is the average atomic mass of titanium on that planet?

Answer : The average atomic mass of Ti is, 46.86 amu

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

As we are given that,

Mass of isotope = 45.95263 amu

Percentage abundance of isotope = 70.300 %

Fractional abundance of isotope = 0.70300

Mass of isotope = 47.94795 amu

Percentage abundance of isotope = 13.700 %

Fractional abundance of isotope = 0.13700

Mass of isotope = 49.94479 amu

Percentage abundance of isotope = 16.000 %

Fractional abundance of isotope = 0.16000

Now put all the given values in above formula, we get:

Therefore, the average atomic mass of Ti is, 46.86 amu

i'm assuming that the correct answer is indeed the first one/ "a"..

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.
