Answer: 2.62 x 10^22 atoms
Explanation:Please see attachment for explanation
I’m not sure if this is what you are referring to but there is something called a moles bridge which allows you to convert from one substance to another
B - False. The crystals have the same internal arrangement of atoms in the same species. For example, all crystals of quartz (Onion, Amethyst, Citrine, Smoky) have the same trigonometrical arrangement.
the atoms in salt (NaCl) are arranged in a cubic way.
Answer:
0.3mol C8H18
Explanation:
For this we must first look at the reaction taking place:
C8H18+O2 --> H2O + CO2
Balancing the equation we get:
2(C8H18)+25(O2) --> 18(H2O) + 16(CO2)
Form there we now need to know how many moles of Octane are needed to produce 2.4moles of H2O. The conversion is as follows:
2.4molH2O ((2mol of C8H18)/(18mol of H2O)) = 0.3mol C8H18
