Answer:
New pressure is 5.40 atm
Explanation:
When T° and moles remain constant, we should use these relation to determine pressure, or also volume
P₁ . V₁ = P₂ . V₂
1.80 atm . 3L = P₂ . 1L
(1.80 atm . 3L ) / 1L = P₂
5.40 atm = P₂
Answer:
it is already balanced bro
Answer:
0.007 moles of octane
Explanation:
Balanced Equation: 2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O
0.065 mol H₂O * 2 mol C₈H₁₈/18 mol H₂O = 0.00722... = 0.007 mol C₈H₁₈
Explanation:
the number of electrons = 8
and protons = 8 can be seen in this atom
We have that
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90
From the question we are told
Find the average atomic mass round and to the second decimal place (0.01)
80% 127I, 17% 126I, 3% 128I
Generally the equation for the Average Mass is mathematically given as
Where
a1 = 127
b1 = 80%
a2 = 126
b2 = 17%
a3 = 128
b3 = 3%
Therefore
In conclusion
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90
