Correct AnswerFourth Option, 2518 g
Solution:The formula of number of moles (n) in terms of mass of the compound(m) and molar mass of the compound (M) can be stated as:
We have the number of moles of Octane.
So,
n = 22.05 moles
We have the molar mass of octane.
So,
M=114.22 g/mol
Using these values in the above formula we can calculate mass of Octane (m).
Therefore, the mass of 22.05 moles of Octane is 2518 g.
Answer
E. 21.3mmHg is the right answer
Answer:
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Explanation:
Answer: Synthesis
0.84 moles of oxygen
25 moles of
Explanation:
The balanced chemical equation is:
This is a synthesis reaction as one product is formed by combination of two reactants.
According to stoichiometry :
a. 2 moles of require = 3 moles of
Thus 0.56 moles of require= of
b. 4 moles of give = 2 moles of
Thus 50 moles of give = of
Answer:
D) Physical property
Explanation:
"A physical property is a characteristic of matter that can be observed and measured without changing the chemical identity of the sample," like color.
