Calculate the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L.
Aleonysh [2.5K]

Answer: 15.5^0C

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 0.987 atm

V = Volume of gas = 12 L

n = number of moles = 0.50

R = gas constant =0.0821Latm/Kmol

T =temperature =  ?

T=\frac{PV}{nR}

T=\frac{0.987atm\times 12L}{0.0820 L atm/K mol\times 0.50mol}=288.5K=(288.5-273)^0C=15.5^0C

Thus the temperature of a 0.50 mol sample of a gas at 0.987 atm and a volume of 12 L is 15.5^0C

The recommended single dose for acetaminophen is 10.0 to 15.0 mg/kg of body weight for adults. Using this guideline, calculate t
marshall27 [118]

Answer:

1.041g is the maximum sigle dose for the person

Explanation:

The maximum dose for acetaminophen is 15.0mg / kg of body weight for adults

To find the maximum single dosage for a person who weighs 153lb we must convert the lb to kg (1lb = 0.4536kg):

153lb * (0.4536kg / 1lb) =<em> 69.4kg is the mass of the person</em>

<em />

As the maximum dose is 15.0mg / kg, the dose of the person is:

69.4kg * (15.0mg acetaminophen / kg) =

<h3>1041mg = 1.041g is the maximum sigle dose for the person</h3>
