Answer : The number of automobiles needed are,
Explanation :
First we have to calculate the mass of blueberries.
As, 1.0 mole of blueberries contains blueberries
So, 0.75 grams of blueberries contains blueberries
Mass of blueberries =
Now we have to calculate the number of automobiles needed.
Number of automobiles needed =
Number of automobiles needed =
Number of automobiles needed =
Thus, the number of automobiles needed are,
Answer:
a) Binding Energy = 1084.266 MeV
b) Binding energy per nucleon = 8.28 MeV
Explanation:
Binding Energy,
Where ΔM = Mass defect of Iodine-131
The mass of iodine-131 = 130.906124 u.
Number of protons in Iodine-131 = 53
Number of neutrons in Iodine-131 = 78
Mass of a proton = 1.007276 u
Mass of neutron = 1.008664 u
Total mass of the 53 protons in Iodine-131 = (53*1.007276)
Total mass of the 53 protons in Iodine-131 = 53.39 u
Total mass of the 78 protons in Iodine-131 = (78*1.008664)
Total mass of the 78 protons in Iodine-131 = 78.68 u
Binding Energy = 1.164 * 931.5
Binding Energy = 1084.266 MeV
b) Binding Energy per nucleon
The mass of the nucleon of iodine 131 = 130.906124
Binding Energy per nucleon = 1084.266/130.906124
Binding energy per nucleon = 8.28 MeV
Answer:
Explanation:
Here, we want to calculate the number of moles of methane in the container
From the ideal gas law:
where:
P is the pressure inside the container which is 3 atm
V is the volume of the container which is 2 L
R is the molar gas constant which is 0.0821 Latm/mol.k
T is the temperature in Kelvin (we convert the temperature in Celsius by adding 273 : 273 + 77 = 350 K)
n is the number of moles that we want to calculate
Substituting the values, we have it that:
