The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The dimensionless standard atomic weight instead refers to the AVERAGE of atomic mass values of a typical naturally-occurring mixture of isotopes for a sample of an element.
You can count it by yourself using formula
m = ({first isotopic distribution%}× {first atomic.mass})+ ({second isotopic distribution%}× {second atomic.mass}) / {100}
To begin calculating, there is one thing you need to remember :
Then we have

The correct option is A.
Climate refers to the long time pattern of weather condition in a particular area. Climate is measured by assessing the patterns of variation in temperature, relative humidity, wind, atmospheric pressure, precipitation and other meteorological variables in a given area over a long period of time.<span />
