Isotope ⁷⁹br has an abundance of 50.69%
Simora [160]

Answer:

79.986

Step-by-step explanation:

Let A represent isotope ⁷⁹Br

Let B represent isotope ⁸¹Br

From the question given above, the following data were obtained:

For Isotope A (⁷⁹Br):

Mass of A = 79

Abundance of A (A%) = 50.69%

For isotope B (⁸¹Br):

Mass of B = 81

Abundance of B (B%) = 49.31%

Relative atomic mass of Br =?

The relative atomic mass (RAM) of Br can be obtained as follow:

RAM = [(Mass of A × A%) /100] + [(Mass of B × B%) /100]

= [(79 × 50.69) /100] + [(81 × 49.31) /100]

= 40.0451 + 39.9411

= 79.986 amu

Thus, the relative atomic mass of Br is 79.986

bob travels from inglewood to Anytown; a distance of 20km. he walks 800m and cycles the rest of the way. What percentage of the
Semmy [17]
We can convert 20km to 20,000m. Then, we can subtract 800m (walking distance) from 20,000m which would result in 19,200m. Then we can put 19,200m and 20,000m as a fraction (19200/20000). Before we can multiply it by 100 to make it in the percentage form, we can get rid of 2 zeroes for both number making it 192/200 and then further simplifying it to 24/25 by dividing both numbers by 8. Finally to get the percentage we can multiply 24 and 100 (2400) and then divide the result (2400) by 25. The final answer is 2400/25=96 meaning he cycled 96% of the journey and walked 4% of the journey (100-96=4).

Simplify (3 to the square of 6)to the square of 18
Zina [86]

Answer:

Evaluate.

Step-by-step explanation:

If you attempt to do the equation 3^{\sqrt{6} }^{^{\sqrt{18} } }, you will get a very long and complicated answer (which is 2.2233078e+21), so I am assuming that is not the question.

If you were to do (3^{\sqrt{6} } ) (\sqrt{18} ), you would get a more rational answer of 62.566.

If you would comment on this post or be more specific on what exactly the question aims to ask, that would be a huge help. :)
