The average dosage of oxcarbazepine for an epileptic child between the ages of 4 and 16 is 9.00 mgmg per 1 kgkg of body weight (

9.00 mg/kgmg/kg). Calculate how many milliliters of oxcarbazepine a child who weighs 42.9 pounds should be prescribed considering the medication is served as a suspension of 60.0 mg/mLmg/mL. Keep in mind that 1 pound is equivalent to 0.453 kilograms.​

Answer:

The answer to your question is 3 ml

Explanation:

Data

Dosage = 9.0 mg/ kg

Child's weight = 42.9 pounds

Suspension = 60 mg/ml

milliliters = ?

Process

1.- Convert the weight to kg

                         1 pound ------------------- 0.453 kg

                     42.9 pounds ---------------  x

                           x = (42.9 x 0.453) / 1

                           x = 19.43 kg

2.- Calculate the milligrams the child needs

                         1 kg of weight ------------ 9 mg

                       19.43 kg ----------------------  x

                            x = (19.43 x 9) / 1

                            x = 174.87 mg of oxcarbazepine

3.- Calculate the milliliters needed

                          60 mg of suspension ------------- 1 milliliters

                        174.87 mg                     --------------  x

                                 x = (174.87 x 1) / 60

                                 x = 2.9 ml ≈ 3 ml

A saturated solution of manganese(II) hydroxide was prepared, and an acid–base titration was performed to determine its KspKsp a
trapecia [35]

Answer:

10.945 x 10^-4

Explanation:

Balanced equation:

Mn(OH)2 +  2 HCl  -->  MnCl2  +  H2O

it takes 2 moles HCL for each mole Mn(OH)2

Next find the molarity of the Mn(OH)2 solution

= (1 mole Mn(OH)2 / 2 mole HCl)  X (0.0020 mole HCl / 1000ml) X (4.86 ml)    

= 4.86 x 10^-3 mole  

this is now dissolved in (70 + 4.86)  =  74.86 ml or 0.07486 L

thus [Mn(OH)2]  =  4.86 x 10^-3 mole / 0.07486 L  =  0.064921 M

Ksp =  [Mn2+][OH-]^2  =  4x^3  =  4(0.064921)^3  = 10.945 x 10^-4

If there are 50 grams of U-238 on day zero of radioactive decay, how much will there be after 4.5 billion years? A) 0.0 grams B)
Natalija [7]

Answer:

= 25 g

Explanation:

Using the formula;

A = A₀ (1/2)^(t/h)

where A is the final amount,

A₀ is the initial amount of the substance,

t is the time and

h is the half-life of the substance,

In this case; the half life of U-238 h is equal to 4.47 billion years.

A = A₀ (1/2)^(t/h)

A = 50 (1/2)^(4.5 / 4.47)

   = 24.88

  <u> = 25 g</u>

Which electron configuration represents an excited state for an atom for calcium
vaieri [72.5K]

The electron configuration that represent an excited state for an atom of calcium is 2, 8, 7, 3.

Calcium atom has an atomic number of 20 and its electronic configuration is 2, 8, 8, 2. An atom is said to be in an excited state if it gains energy and move to an higher energy level. For the calcium atom given above, there are 20 electrons which are distributed into four shells. But in the excited state [option 3], one of the 8 electrons in the third shell gains energy and move to the fourth shell. Thus, the number of electrons in the third shell reduced by 1, while the number of electrons in the fourth shell increase by 1.
