Answer:

4.68x10⁻⁵N

Explanation:

The pH is defined as -log [H⁺]. If an acid has a pH of 4.33, [H⁺] is:

pH = -log [H⁺]

4.33 = -log [H⁺]

10^(-4.33) = [H⁺]

4.68x10⁻⁵M = [H⁺]

The [H⁺] is in molarity units, that is mole / L. Normality has as units equivalent / L. As the equivalent in an acid-base reaction is defined as the number of moles of H⁺, in this case:

4.68x10⁻⁵M = 4.68x10⁻⁵N

Calculate the total number of days therapy available within a 300 ml bottle of ranitidine (as hydrochloride) 75 mg/5 ml. oral so

Lisa [10]

Answer: This therapy is available for 15 days.

Explanation:

We are given:

Oral solution dosage = 75 mg/5 mL

To calculate the volume of oral situation for single dose per, we use unitary method:

The volume required for 75 mg of solution is 5 mL

So, the volume required for 300 mg of solution will be = $\frac{5mL}{75mg}\times 300mg=20mL$

The total volume of the ranitidine bottle = 300 mL

To calculate the number of days, we divide the total volume of the bottle by the volume of dose taken per night, we get:

$\text{Number of days}=\frac{\text{Total volume}}{\text{Volume of dose taken per night}}=\frac{300mL}{20mL}=15$

Hence, this therapy is available for 15 days.

VikaD [51]

Answer:

2.5 moles of NaCl

Explanation:

The balanced chemical reaction equation is shown in the image. Since it takes 2 moles of Hydrochloric acid to form two moles of sodium. Chloride, then 2.5 moles of hydrochloric acid should also form 2.5 moles of sodium chloride according to the balanced reaction equation.
