Explanation:

The two isotopes of lithium given are similar in the sense that they have the same atomic number which is 3.

Every kind of an atom of an element have the same atomic number. Atomic number is the number of protons in an atom.

The atoms are different in that they have different mass number because the number of protons they contain are different.

So for isotopes;

  • They have the same electronic configuration
  • They have similar chemical properties
  • But their masses differs
  • Their abundance in nature also differs.

Anastasy [175]

Answer:

2.4 capsules

Explanation:

You are to give ampicillin, with a recommended dose of 25 mg/kg (25 mg of ampicillin per kg of body weight), to a child with a mass of 24 kg. The mass of ampicillin to be given is:

24 kg body mass × (25 mg ampicillin/ 1 kg body mass) = 600 mg ampicillin

The stock on hand is 250 mg/capsule (250 mg ampicillin per capsule). The number of capsules required to supply 600 mg of ampicillin is:

600 mg ampicillin × (1 capsule/250 mg) = 2.4 capsule
