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>
In a balanced chemical equation, the numbers of individual particles and the numbers of moles of particles are represented by the COEFFICIENTS.

I think the answer is C. 02
Answer:
New volume is 14.35 mL
Explanation:
When a system of a gas keeps on constant its temperature and number of moles, the pressure is modified indirectly proportional to the volume:
Pressure increased → Volume decreased
Pressure decreased → Volume increased.
The relation you have to apply is: P₁ . V₁ = P₂. V₂
1.23 atm . 35 mL = 3 atm . V₂
(1.23 atm . 35 mL / 3 atm) = V₂
V₂ = 14.35 mL
