    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 00 g of ch4
