A cat requires a 3 ml injection of a 5% solution how many milligrams what receive per injection

150 mg

Step-by-step explanation:

1. Calculate the mass of the injection

The density of water is 1 g/mL.

Mass = 3 mL injection * (1 g injection/1 mL injection) = 3 g injection

2. Convert to grams to milligrams

1000 mg = 1 g

3 g injection * (1000 mg injection/1 g injection) = 3000 mg injection

3. Calculate the mass of medication

3000 mg injection * 5 mg medication/100 mg injection = 150 mg medication

The cat will receive 150 mg of medication per injection.
