It's not really possible to tell longitudinal vs. transverse in this image as given. However, we can say that the waves labeled A are high-frequency (short wavelengths) while the waves labeled B are low-frequency (long wavelengths). So, this third answer choice would be correct here.
A believe it’s called a “group”
Correct me if I’m wrong!
The volume (in mL) of the 1.00 M LiOH needed to prepare 500.00 mL of 0.075 M of LiOH is 37.5 mL
<h3>How do I determine the volume (in mL) of LiOH needed?</h3>
Dilution formula is given as follow:
M₁V₁ = M₂V₂
Where
- M₁ is the molarity of stock solution
- V₁ is the volume of stock solution
- M₂ is the molarity of diluted solution
- V₂ is the volume of diluted solution
Applying the above formula, we obtain the volume (in mL) of LiOH needed to prepare 500.00 mL of 0.075 M of LiOH. This is illustrated below:
- Molarity of stock solution of LiOH (M₁) = 1.00 M
- Volume of diluted solution of LiOH (V₂) = 500.00 mL
- Molarity of diluted solution of LiOH (M₂) = 0.075 M
- Volume of stock solution of LiOH needed (V₁) =?
M₁V₁ = M₂V₂
1 × V₁ = 0.075 × 500
V₁ = 37.5 mL
Thus, the volume (in mL) of LiOH needed is 37.5 mL
