Answer:
58.443 g/mol
Explanation:
The molar mass of NaCl is the sum of the molar masses of the individual atoms:
Na: 22.989770 g/mol
Cl: 35.453 g/mol
The total molar mass is ...
NaCl: 58.443 g/mol
__
The molar mass does not depend on whether the material is in solution or in any other form.
Answer:
The final volume in mL is 7.14 mL or 7.1 mL.
Explanation:
1.Use Boyle's Law(
). Re-arrange to solve for 
<em> for the final volume.</em>

<em>2. Plug in values. </em>
Staining specimen with heavy metal salts (e.g. tungsten, molybdenum) allows you to see the specimen better with higher contrast when electron beam deflects off of your sample.
