Answer:
0.50 M
Explanation:
Given data
- Mass of sodium sulfate (solute): 7.1 g
- Volume of solution: 100 mL
Step 1: Calculate the moles of the solute
The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:

Step 2: Convert the volume of solution to liters
We will use the relation 1 L = 1000 mL.

Step 3: Calculate the molarity of the solution

Answer:
The average mass of all isotopes of the element
Explanation:
Mass number is most similar to the average mass of all isotopes of the element. Mass number = number of protons +number of neutrons, and it is a mass of one of the type of isotope.
