What is the solution to the problem expressed to the correct number of significant figures? 12.0/7.11=?

xxMikexx [17]

Answer:

1.69.

Explanation:

The solution = 12.0 / 7.11 = 1.687 = 1.69.

The rule of significant figures for division states that: the results are reported to the fewest significant figures.

12.0 contains 3 significant figures.

7.11 contains 3 significant figures.

So, the solution should contain 3 significant figures.

Now, the issue id of rounding; In a series of calculations, carry the extra digits through to the final result, then round.

If the digit to be removed is equal to or greater than 5, the preceding digit is increased by 1.

The digit that should be removed is 7 that is larger than 5 so increase the preceding digit by 1.

Answer:

Average atomic mass = 10.812 amu

Explanation:

The formula for the calculation of the average atomic mass is:

$Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})$
