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 (
Helga [31]

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 large piece of jewelry has a mass of 132.6 g. a graduated cylinder initially contains 48.6 ml water. when the jewelry is sub
elena-s [515]

The large piece of jewelry  that has a mass of 132.6 g and when is submerged in a graduated cylinder that initially contains 48.6 ml water and the volume increases to 61.2 ml once the piece of jewelry is submerged, has a density of: 10.523 g/ml

To solve this problem the formulas and the procedures that we have to use  are:

  • v = v(f)-v(i)
  • d = m/v

Where:

  • d= density
  • m= mass
  • v= volume
  • v(f) = final volume
  • v(i) = initial volume

Information about the problem:

  • m = 132.6 g
  • v(i) = 48.6 ml
  • v(f) = 61.2 ml
  • v = ?
  • d =?

Applying the volume formula we get:

v = v(f)-v(i)

v = 61.2 ml - 48.6 ml

v = 12.6 ml

Applying the density  formula we get:

d = m/v

d = 132.6 g/12.6 ml

d = 10.523 g/ml

<h3>What is density?</h3>

It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
