photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
The largest number of molecules is the same as the largest number of moles of this molecules
to calculate the number of moles you have to divide the mass by the molar mass
molar masses:
CO2: 44,01 g/mol
CH4: 16,04 g/mol
CBr4: 331,63 g/mol
CHBr3: 252,73 g/mol
largest nº of mol= 100/(the smallest molar mass possible)
= 100/16,04
=6,23 moles
all other molecules would be smaller than 6,23 moles because the molar mass is so high.
The answer is B : 1<span>00 g of ch4</span>
Answer:
Explanation:
Hello!
In this case, since the molar mass of a chemical compound is computed by averaging the atomic mass of each element in the molecule and the amount of atoms; which in this case there are 9 carbon atoms, 13 hydrogen atoms, 1 nitrogen atom and 3 oxygen atoms; thus, we compute the average as shown below:
Now, we plug in the atomic masses to obtain:
