Answer:
Explanation:
Hello,
In this case, considering the given chemical reaction, we can use the molar mass of octane (114.23 g/mol) and the 2:16 molar ratio with carbon dioxide to compute the emitted moles of CO2 to the atmosphere via the following stoichiometric procedure:
Which also corresponds to the following mass:
Best regards.
Answer:
1.2044 x 10^24 particles
Explanation:
Assuming this is<u> STP</u>....then this is 2 moles ( each mole = 22.4 L/mole)
2 moles = 2 * 6.022 x 10^23 = 1.2044 x 10^24
For every mole of any substance or element, the total number of atoms is 6.022 x 10^23. This is called the avogadro's number. Hence, for a) for a 0.90 mole copper, the number of atoms is 5.42 x10^23. This also applies for B) which gives silver as given. For c), the number of molecules present in a compound is also the same. Thus, for a,b,and c, the answer is 5.42 x10^23.
Because the most dense part of an atom is the nucleus. Not the electron cloud.
I believe your answer is 40g 15*C I hope that helps.
