Juliette [100K]

Answer:

The pressure is $P_f = 0.93 \ atm$

Explanation:

From the question we are told that

The volume of Ne is $V_N = 2.50 \ L$

The volume of CO is $V_C = 2.00 \ L$

The pressure of $Ne$ is $P_N = 1.09 \ atm$

The pressure of CO is $P_C = 0.773 \ atm$

The number of moles of Ne present is evaluated using the ideal gas equation as

$n_N = \frac{P_N * V_N}{R T}$

=> $n_N = \frac{1.09 * 2.50 }{R T} = \frac{2.725}{RT}$

The number of moles of CO present is evaluated using the ideal gas equation as

$n_N = \frac{P_C * V_C}{R T}$

=> $n_N = \frac{0.73 * 2.00 }{R T} = \frac{1.46}{RT}$

The total number of moles of gas present is evaluated as

$n_T = n_N + n_C$

$n_T = \frac{2.725}{RT} + \frac{1.46}{RT}$

$n_T = \frac{4.185}{RT}$

The total volume of gas present when valve is opened is mathematically represented as

$V_T = V_N + V_C$

=> $V_T = 2.50 + 2.00 = 4.50 \ L$

From the ideal gas equation the final pressure inside the system is mathematically represented as

$P_f = \frac{n_T * RT }{ V_T}$

=> $P_f = \frac{[\frac{4.185}{RT} ] * RT }{ 4.50}$

=> $P_f = 0.93 \ atm$

Acetaminophen (C8H9NO2) is the active ingredient in many nonprescription pain relievers. Each tablet contains 500 mg of acetamin

ohaa [14]

1) Molar mass C8H9NO2

Element Atomic mass    # of atoms mass
   g/mol g
C 12 8 12*8 = 96
H 1 9    1*9 = 9
N    14    1    14*1 = 14
O    16 2 16*2 = 32

      molar mass = 96 + 9 + 14 + 32 = 151 g/mol

2) Number of mols in a tablet

# of moles = mass / molar mass = 0.500 g / 151 g/mol = 0.003311 moles

3) 3 doses * 2 tablets * 0.003311 moles / tablet = 0.020 moles
