Answer:
0.8853 mL
Explanation:
First we <u>convert 13 lb to kg</u>, keeping in mind that <em>1 lb = 0.454 kg:</em>
- 13 lb *
= 5.902 kg
Then we <u>calculate how many mg of acetaminophen should be given</u>, using the <em>recommended dose and infant mass</em>:
- 15 mg/kg * 5.902 kg = 88.53 mg
Finally we<u> calculate the required mL of suspension</u>, using its <em>concentration</em>:
- 88.53 mg ÷ (80 mg/0.80 mL) = 0.8853 mL
Answer: Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of and a pressure of 15200 kPa
Explanation:
According to ideal gas equation:
P = pressure of gas = 15200 kPa =150 atm (1kPa=0.0098atm)
V = Volume of gas = 47 L
n = number of moles = ?
R = gas constant =
T =temperature =
Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of and a pressure of 15200 kPa
