To accomplish this, we must first understand the rules of significant figures.
<span>Rule #1: All digits other than zero are considered significant. (1234)
Rule #2: Leading zeros do not count as significant. (0.093)
Rule #3: Zeros situated between non-zero digits are significant. (78309)
Rule #4: Trailing zeros are significant only if there is a decimal point. (0.05470)
Therefore, considering these rules, 56.0g contains three significant figures due to the decimal point.
0.0004m has just one significant figure per Rule #2.
1003ml contains 4 significant figures because the zeros are between two significant digits.
Lastly, 0.0350s has 3 significant figures because digits following a decimal point are counted.

The isotopic mass of 47Z is calculated to be 46.96 amu. Isotopes of a single element differ in neutron count, and to ascertain the relative atomic mass, we consider each isotope's mass weighted by their natural abundance. This provided a computation to derive the mass of 47Z.
Answer:
The response is provided below.
Explanation:
Numerous aspects can influence the actual results of titration. These factors vary from human error to misjudging measurements, a researcher's interpretation of color changes, and improper techniques during the experimental procedure.
Thus, to mitigate these errors, researchers must engage thoroughly throughout experimentation, and employing gross readings can assist in reducing mistakes when determining the final titre value.
The solution to your inquiry is: c = a + b - d. In the chemical equation aA + bB → cC + dD, c may take any value from 1 to however many are needed for the equation to maintain its balance. For instance, if we consider c + d = a + b, we can express c as a + b - d. If we assign values a = 1; b = 3, and d = 2, then c equals 1 + 3 - 2, resulting in c = 2, and so forth.
