Q3) 1.5 mL from the 1.00 M HCl stock solution

Q4) 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

Explanation:

Q3) Determine the amount of 1.00 M HCl stock solution needed to form 100 mL of 1.50 × 10⁻² M HCl solution.

Q4)  Determine the amount of 1.00 × 10⁻¹ M stock NaOH solution needed to form 100 mL of 1.50 × 10⁻² M NaOH solution.

To solve both of the questions we use the following formula:

initial concentration × initial volume =  final concentration × final volume

For Q3 we have:

initial concentration = 1.00 M HCl

initial volume = ?

final concentration =  1.50 × 10⁻² M HCl

final volume = 100 mL

1.00 × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00

initial volume = 1.5 mL from the 1.00 M HCl stock solution

For Q4 we have:

initial concentration = 1.00 × 10⁻¹ M NaOH

initial volume = ?

final concentration =  1.50 × 10⁻² M NaOH

final volume = 100 mL

1.00 × 10⁻¹ × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00 × 10⁻¹

initial volume = 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

TRUE OR FALSE
lesantik [10]
It depends on what unit/subject you're looking at.

Because in physics, I know that if you are considering Newton's theory of particles, all particles technically go in a straight line from the original direction. BUT, if you're looking at the Wave of the Particle theory, then you would assume that particles do not necessarily follow the above b/c they follow the properties of a wave...
