The amount of Amoxicillin dose given to the 85.4 lb child daily is determined as 1,743.3 mg.

<h3>What is the amount of Amoxicillin dose given to the child?</h3>

The amount of  Amoxicillin  dose given to the child is calculated as follows;

amount of Amoxicillin dose = weight of the child x dosage prescribed

<h3>What is the weight of the child in pounds (lb) </h3>

The weight of the child in pounds (lb) is calculated as follows;

1 lb = 0.453592 kg

85.4 lb = ?

= 85.4 x 0.453592 kg

= 38.74 kg

amount of Amoxicillin dose = 38.74 kg x 45 mg/kg

amount of Amoxicillin dose = 1,743.3 mg

Thus, the amount of Amoxicillin dose given to the 85.4 lb child daily is determined as 1,743.3 mg.

For an aqueous solution of sodium chloride (NaCl) .Determine the molarity of 3.45L of a solution that contains 145g of sodium
worty [1.4K]
Molar mass NaCl = 58.44 g/mol

number of moles:

mass NaCl / molar mass

145 / 58.44 => 2.4811 moles of NaCl

Volume = 3.45 L

Therefore :

M = moles / volume in liters:

M = 2.4811 / 3.45

M = 0.719 mol/L⁻¹

 The mass  percent  of potassium chloride  is   1.386%

<u><em>calculation</em></u>

mass  percent = actual mass/ Theoretical mass x 100

Actual mass = 9.35 g

Theoretical mass  is  calculated as below

Step 1 : write the equation for reaction

KCl + H₂O  →   KOH + HCl

Step 2: find the moles of H₂O

moles = mass÷ molar mass

The molar mass of H₂O = (2 x1 ) +(16)  = 18 g/mol

moles is therefore = 162.98 g÷ 18 g/mol =9.054 moles

Step 3: use the mole ratio to determine the moles of KCl

KCl: H₂O  is 1:1 therefore the moles of KCl  is also = 9.054 moles

Step 4:  find the  theoretical mass of KCl

mass = moles x molar mass

from periodic table the  molar mass of KCl = 39 +35.5 =74.5 g/mol

mass = 9.054 moles x 74.5 g/mol =674.5 g


Theoretical mass is therefore = 9.35 g/ 674.5 g x 100 = 1.386%

Which substances ionize when they dissolve?
noname [10]
<h3>Answer:</h3>

Ionic compounds

<h3>Explanation:</h3>

What are ionic compounds?

  • Ionic compounds are compounds that are formed due to ionic bonds between atoms.
  • Ionic bonds are formed between metallic atoms and non-metallic atoms.

What are examples of ionic compounds?

  • Examples of ionic compounds include, KCl, NaBr, MgCl₂, etc

How do ionic compound ionize in water?

  • Ionic compounds ionizes when dissolved in water to form mobile ions.
  • When dissolved in water they may serve as electrolytes due to the presence of free ions which will be responsible for conduction of electricity.
  • For example, NaCl ionizes to form Na⁺(aq) and Cl⁻(aq).
