Pressure of argon = 546.8 kPa
Conversion factor: 1 atm = 101.325 kPa
Pressure of argon = 546.8 kPa x 1 atm/101.325 kPa = 5.4 atm
Moles of argon = 15.82
Volume of argon = 75.0 L
According to Ideal gas law,
PV = nRT
where P is the pressure, V is the volume , n is the number of moles, R is the universal gas constant, and T is the temperature
T = PV/nR = (5.4 atm x 75.0 L) / (15.82 x 0.0821 L.atm.mol⁻¹K⁻¹)
T = 311.82 K
Hence the temperature of the canister is 311.82 K.
To solve this problem,
we must first examine the chemical formula of an alkene (CnH2n) and notice that
there are 2 H atoms for every 1 C atom.
<span>
Therefore this means that we can calculate the
weight percent of Hydrogen (H) using the molecular formula: </span>
<span>wt% H2 = 2n * (1.0g/mol H)/[2n*(1.0g/mol H) + n*(12.0g/mol
C)) x 100 = 14.3 wt% H
So for any alkene with mass of 0.561g, this contains
(0.143)x(0.561g) = 0.080 g H
Now, we calculate the number of moles of H this is by
dividing with the molar mass:
moles H = (0.080g H) / (1.00 g/mol H) = 0.08 moles H.
We know that there are 0.5 moles of water per mole of hydrogen,
therefore the moles of H2O formed is:
moles H2O = 0.5 * moles H = 0.5 * (0.08) = 0.04 moles H2O</span>
Answer:
<span>0.04 moles water</span>
yes, because though some are skeptical of vaccinations, vaccines will ultimately help a child become immune to certain viruses, rendering those specific viruses harmless to the child
I did this already and i put this down :3 <span>first you would separate each part of the beach into three zones one for basic cleaning another for harder work and then animal searching and cleaning and release, after that you would begin to work on the sections one by one using certain tools and a large amount of effort being used, then finally you end with a cleaned up beach clean water and safe animals and happy faces from people as well.</span>
