Question

What is meant by solution?​

Answer 1

Given :

{\sf{Bromine}}Bromine atom is available in the form of, say, two isotopes {\sf{{}^{79}_{35}Br}}

35

79

Br {\sf{(49.7 \%)}}(49.7%) and {\sf{{}^{81}_{35}Br}}

35

81

Br {\sf{(50.3 \%)}}(50.3%)

To find :

The average atomic mass of bromine atom.

Solution :

We know that ,

% of Br (79) = 49.7 ; % of Br (81) = 50.3

\sf Average \: atomic \: mass \: of \: Be = {\sf{{}^{79}_{35}Br}} AverageatomicmassofBe=

35

79

Br

\sf Average \: atomic \: mass \: of \: Br = {\sf{{}^{79}_{35}Br}} \times percent + atomic \: mass \: of \: Br \times percentage /100AverageatomicmassofBr=

35

79

Br×percent+atomicmassofBr×percentage/100

\sf \red {=[79×49.7 + 81×50.3]/100}=[79×49.7+81×50.3]/100

\sf \green{=80.00}=80.00

The average atomic mass of bromine atom is 80 .

Solution, in chemistry, a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible.
