The concentration of phenylephrine hydrochloride in a prefilled syringe is 10 mg/mL. What is the percentage concentration (w/v)

mihalych1998 [28]

Answer:

The percentage concentration (w/v) of phenylephrine in the injection is 1 %.

Explanation:

The percentage concentration in w/v of the phenylephrine hydrochloride can be calculated as follows:

$\%^{w}/_{v} = \frac{m}{V} \times 100$

Where:

m: is the mass of the solute in grams

V: is the volume of the solution in milliliters

The concentration of the phenylephrine hydrochloride is 10 mg/mL, so the percentage concentration is:

$\%^{w}/_{v} = \frac{m}{V} \times 100$

$\%^{w}/_{v} = \frac{10 \cdot 10^{-3} g}{1 mL} \times 100$

$\%^{w}/_{v} = 1 \%$

Therefore, the percentage concentration (w/v) of phenylephrine in the injection is 1 %.

I hope it helps you!

fgiga [73]

Answer:

Here's what I get.

Explanation:

According to Markovnikov's rule, the H will add to a terminal carbon, generating three resonance stabilized carbocations.

The Br⁻ ion will add to any of the three carbocations.

There are three possible products:

5-bromo-2,5-dimethylhexa-1,3-triene (1)
3-bromo-2,5-dimethylhexa-1,4-triene (<em>2</em>)
1-bromo-2,5-dimethylhexa-2,4-triene (3)

Which quantity can be calculated using the equation E=MC^2

r-ruslan [8.4K]

Answer:

The energy needed to split an atom into separate protons, neutrons, and electrons

Explanation:

The equation E = MC^2 is developed by Einstein’s Special Relativity Theory

where,

E = Energy

M = mass

C = speed of the light

The energy should be measured in Joules i.e J

The mass should be measured in Kilogram i.e Kg

And, the speed of the light should be measured in meters per second i.e ms-1

The C should be squared

Now the energy is required to divided into three particles i.e protons, electrons and neutrons

It also needs to allocate the nucleus into distinct protons and neutrons that we called binding energy of nuclear

And if the energy is required to take off an electron from an atom we called the energy of ionization

And if the energy is required to add an electron to an atom so we called it affinity of electron
