First, determine the number of moles of butane you have. Start with the atomic weights of the involved elements:
Atomic weight carbon = 12.0107
Atomic weight hydrogen = 1.00794
Atomic weight oxygen = 15.999
Molar mass butane = 4*12.0107 + 10*1.00794 = 58.1222 g/mol
Moles butane = 2.20 g / 58.1222 g/mol = 0.037851286
Looking at the balanced equation for the reaction which is
2 C4H10(g)+13 O2(g)→8 CO2(g)+10 H2O(l)
It indicates that for every 2 moles of butane used, 8 moles of carbon dioxide is produced. Simplified, for each mole of butane, 4 moles of CO2 are produced. So let's calculate how many moles of CO2 we have:
0.037851286 mol * 4 = 0.151405143 mol
The ideal gas law is
PV = nRT
where
P = Pressure
V = Volume
n = number of moles
R = Ideal gas constant ( 0.082057338 L*atm/(K*mol) )
T = absolute temperature (23C + 273.15K = 296.15K)
So let's solve the formula for V and the calculate using known values:
PV = nRT
V = nRT/P
V = (0.151405143 mol) (0.082057338 L*atm/(K*mol))(296.15K)/(1 atm)
V = (3.679338871 L*atm)/(1 atm)
V = 3.679338871 L
So the volume of CO2 produced will occupy 3.68 liters.</span>

Answer:
A and E
Explanation:
Backbone is the part of skeletal system and is made of 26 vertebrae in total. The backbone and bones of lower limbs together serve to support the body's weight. Backbone surrounds and protects the spinal cord. Since the vertebrae of backbone are joints together by synovial joints, it allows the flexibility and movement of organisms.
Answer:
The new pressure is 3850 torr.
Explanation:
The relation between volume and pressure is inverse as per Boyle's law. Its mathematical form is given by :
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
Here,
![P_1=2.9\ atm](https://tex.z-dn.net/?f=P_1%3D2.9%5C%20atm)
![V_1=707\ mL](https://tex.z-dn.net/?f=V_1%3D707%5C%20mL)
![V_2=0.533\ L](https://tex.z-dn.net/?f=V_2%3D0.533%5C%20L)
Let
is the new pressure. So using Boyle's law we get :
![P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{2.9\times 707}{0.533}\\\\P_2=3846.71\ \text{torr}](https://tex.z-dn.net/?f=P_2%3D%5Cdfrac%7BP_1V_1%7D%7BV_2%7D%5C%5C%5C%5CP_2%3D%5Cdfrac%7B2.9%5Ctimes%20707%7D%7B0.533%7D%5C%5C%5C%5CP_2%3D3846.71%5C%20%5Ctext%7Btorr%7D)
or
![P_2=3850\ \text{torr}](https://tex.z-dn.net/?f=P_2%3D3850%5C%20%5Ctext%7Btorr%7D)
So, the new pressure is 3850 torr.
