What is the molarity of the solution formed by mixing 0.20mol of sodium hydroxide with enough water to make 150 ml of solution?
bixtya [17]
Molarity is defined as the number of moles of solute in 1 L of solution 
number of NaOH moles present - 0.20 mol 
volume of solution - 150 mL 
since molarity is taken as number moles of solute in 1000 mL
if 150 mL contains - 0.20 mol 
then 1000 mL should contain - 0.20 / 150 x 1000 = 1.33 mol 
therefore molarity is 1.33 M

Graduated cylinder is filled to 41.5mL with water, and a price of granite is placed in the cylinder displacing the level to 47.6
Y_Kistochka [10]

Answer:

6.1 cm³

Explanation:

To solve this problem we first need to keep in mind <em>Archimedes' principle</em>:

  • The volume of water (or any fluid) displaced by a submerged object is equal to the object's volume.

With that in mind we <u>calculate the volume of the granite piece in mililiters</u>:

  • Volume displaced = 47.6 mL - 41.5 mL = 6.1 mL
  • Volume of the granite piece = 6.1 mL

Given that one cubic centimeter is equal to one mililiter, the volume of the granite piece in cm³ is 6.1 cm³.

Is more chemical weathering likely to occur in New York location or in the Illinois location? Explain your answer. HELP NEEDED (
Naily [24]
The pH of pure water is 7.0, which is neutral.

For a pH below this, the water is acidic. Substances that are acidic are often corrosive and thus could cause weather damaging. The pH of the precipitation in NY is below that of the precipitation in IL, and NY receives more precipitation, so for both of those reasons, it is likely to have more chemical weathering.
