Question

a scientist is determining the mass of 33,000 molecules of oxygen. use this to answer parts a and b. a. how many significant digits should be in the solution? there should be significant digits in the solution. (type a whole number.) the mass of one molecule of oxygen = 5.3×10^(-23) gram.

Explanation:

Step1: Identify significant - digits rule

When multiplying or dividing, the number of significant digits in the result is determined by the number with the fewest significant digits among the values used in the calculation.

Step2: Analyze given values

The number of molecules is 33,000 (2 significant digits if we assume the trailing zeros are not significant, which is a common - sense assumption without further context), and the mass of one molecule is \(5.3\times10^{- 23}\) g (2 significant digits).

Answer:

2
