The average atomic mass is 6.92X
How do we compute the average atomic mass?
In a bid to calculate the average atomic mass, we multiply the fraction of each isotope by the mass number , then add them together.
This is more like weighted average, as shown below:
average atomic mass=(mass number of first isotope*fraction)+(mass number of second isotope*fraction)
average atomic mass=(6X*7.59%)+(7X*92.41%)
average atomic mass= 6.92X

FACTORISATION IS BASICALLY FINDING LIKE-TERMS.
1. FIND THE HCF OF 8. HERE, THE HCF IS 8. ALSO, CHECK ALL THE LIKE-TERMS. LIKE-TERMS ARE OUTSIDE THE BRACKET AND UNLIKE TERMS ARE INSIDE.
2. ADD THE TERMS IN THE BRACKET AND THE TERMS OUTSIDE THE BRACKET FROM STEP 1.
8x + 8y + rx + ry
1. 8 (x + y) + r (x + y)
2. (x +y) (8+r)
