Answer:
The volume of the gas is 0.015 m^3.
Explanation:
mass, m = 32 g
Temperature, T = 45 °C = 45 + 273 = 318 K
Pressure, P = 728 mm of hg = 0.728 x 13.6 x 1000 x 9.8 = 97027.84 Pa
Atomic mass = 4 x 12 + 10 x 1 = 58 g
Use the ideal gas equation
Let the volume is V.
P V = n R T
Answer:
21.344%
Explanation:
For the given chemical reaction, 8 moles of the reactant should produce 4 moles of 
. However, 195 g of was produced instead. The molar mass of is 61.9789 g/mol.
Thus, the moles of produced = 195/61.9789 = 3.1462 moles
The percent error = [(Actual -Experiment)/Actual]*100%
The percent error = [(4.00 - 3.1462)/4.00]*100% = (0.85376/4.00)*100% = 21.344%

Basically, an electron dot diagram is just a diagram showing the number of valence electrons a certain atom has (valence electrons are electrons in the outer-most electron level of an atom). The 5 steps they give you just tell you the order of where to put each dot. The picture I attached gives a better representation.
The number around the symbol shows the order of where you would put the dot. The 1 and the 2 on the top show that the first two dots go there, and the 3, 4, and 5 go around the rest of the sides. When it gets to 6, 7, and 8, the numbers go back around to fill in each side twice.
