    Exercise \(\PageIndex{1}\)

    How many grams of sodium bicarbonate are contained in a 300 mL solution of 1.35% w/v sodium bicarbonate?

    Exercise \(\PageIndex{2}\)

    How many grams of sodium bicarbonate are contained in a 175 mL solution of 1.85% w/v sodium bicarbonate?

    Exercise \(\PageIndex{3}\)

    Using a saline solution that is 0.75% w/v, how many milligrams of sodium chloride are in 150 mL?

    Exercise \(\PageIndex{4}\)

    Using a saline solution that is 1.25% w/v, how many milligrams of sodium chloride are in 200 mL?

    Exercise \(\PageIndex{5}\)

    A prescription calls for a patient to receive 23 mg daily of a drug to be taken in pill form for 5 days. If the pills are available in 5.75 mg, how many pills will the patient need for the full prescription run?

    Exercise \(\PageIndex{6}\)

    A prescription calls for a patient to receive 21 mg daily of a drug to be taken in pill form daily. If the pills are available in 3.5 mg, how many pills will the patient need each day?

    Exercise \(\PageIndex{7}\)

    A patient is prescribed 4mg/kg of a drug to be delivered daily intramuscularly, divided into 2 doses. If the patient weighs 30 kg, how many milligrams of the drug would be needed for each dose?

    Exercise \(\PageIndex{8}\)

    A patient is prescribed 1.5 mg/kg of a drug to be delivered intramuscularly, divided into 3 doses per day. If the drug is available in 12.5 mg/mL and the patient weighs 50 kg, how many milliliters of the drug would be given per dose?

    Exercise \(\PageIndex{9}\)

    A patient is prescribed 0.5 mg/kg of a drug to be delivered intramuscularly, divided into 2 doses per day. If the drug is available in 2.5 mg/mL and the patient weighs 45 kg, how many milliliters of the drug would be given per dose?

    Exercise \(\PageIndex{10}\)

    A patient is prescribed 1.5 mg/kg of a drug to be delivered intramuscularly, divided into 3 doses per day. If the drug is available in 30 mg/mL and the patient weighs 54 kg, how many milliliters of the drug would be given per dose?

    For the following exercises, use the mathematical modeling graph showing contact tracing for students in a particular class.

    A graph represents contact tracing. The graph shows Justin at the center. Four lines from Justin lead to Nara, Luka, Kalina, and Tai. A line from Tai leads to Pasha. A line from Pasha leads to Javier. A line from Kalina leads to Javier. A line from Kalina leads to Luka. A line from Luka leads to Hani. A line from Hani leads to Nima. A line from Nima leads to Nara. A line from Nara leads to Aili. Two lines from Aili lead to Loise and Emmet. A line from Loise leads to Emmet.

    Exercise \(\PageIndex{11}\)

    List the people who have a length of 2 from Justin.

    Exercise \(\PageIndex{12}\)

    Find 2 paths of with a length of 3 from Emmet.

    Exercise \(\PageIndex{13}\)

    Find the shortest path from Aili to Kalina.

    Exercise \(\PageIndex{14}\)

    Which people does the model show as directly in contact with Nara?

    Exercise \(\PageIndex{15}\)

    Find the shortest path from Tai to Hani.

    Exercise \(\PageIndex{16}\)

    Of the 12 people in the model, how many have a path of 2 or less from Justin?
