Explanation:

1) Data:

a) Chemical formula: C₆H₁₂O₆

b) Molecular weight, MM = 180.16 g/mol

c) mass, m = 19.1 g

c) n = ?

2) Formula:

3) Soltuion:

Substitute the data:

The significant figures start with the first non-zero digit after the decimal point, so they are 1, 0, and 6, i.e. three significant figures.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

b.false that your answer
