Measured values are verified and go under a series of experiments before being accepted as the norm. Accepted values are unanimously accepted values, seen as the norm by a qualified group of individuals (scientists or the people of the intellectual sphere).
Answer: There are 0.056 moles present in 3.45 g of
.
Explanation:
Given : Mass = 3.45 g
Moles is the mass of substance divided by its molar mass.
Hence, moles of
(molar mass = 61.98 g/mol) is as follows.

Thus, we can conclude that there are 0.056 moles present in 3.45 g of
.

This problem is providing a mathematical expression which the result should be expressed with the correct significant figures. At the end, the result is 1209.0 because of the following:
<h3>Significant figures:</h3>
In science, the use of significant figures is crucial as long numbers are not necessarily required when reporting a numerical value, for that reason the importance of reporting measurements with the correct number of significant figures.
In the case of additions, we perform the normal operation as the first step:
1204.2 +4.79613 = 1208.99613
Next, we round the result to the least number of decimal places, in this case one because 1204.2 has just one decimal place, unlike the 4.79613 which has five, so that we round the 8 up to 9 and leave a 0 as the only decimal place:
1209.0
