We will use Ideal gas equation.
PV=nRT
where
P= pressure(in atm)=5.82atm
V=Volume=?
n= moles of gases=0.682
R = gas constant= 0.0821L atm / mol K
T = temperature= 68.2 C= 68.2 + 273.15 = 341.35 K
V= nRT/ P= 0.682 X 0.0821 X 341.35/ 5.82
V= 3.284 L.
The atomic mass number does<span> not change because a </span>beta<span> particle has a much smaller </span>mass<span> than the </span>atom<span>. The </span>atomic number<span> goes up because a neutron has turned into an extra proton. </span>Beta decay<span> is fundamentally different from alpha </span>decay<span>.

There are things that should be concerned about eating peanut butter. One would be the toxic fungus found within the peanut. Non-organic peanuts and peanut butters are also contaminated with pesticides.Peanuts also contain another natural substance called oxalates which can be toxic to the body.
Answer:
See below.
Explanation:
The mass of octane in the sample of gasoline is 0.02851 * 482.6 = 13.759 g of octane.
The balanced equation is:
2C8H18(l) + 25O2(g) ----> 16CO2(g) + 18H2O(g)
From the equation, using atomic masses:
228.29 g of octane forms 704 g of CO2 and 324.3 g of H2O
So the mass of CO2 formed from the combustion of 13.759 g of octane = (704 * 13.759) / 228.29
= 42.43 g of CO2.
Amount of water = 324.3 * 13.759) / 228.29
= 19.55 g of H2O.
