Related: Molecular weights of amino acids Weights of atoms and isotopes are from NIST article. Mass of butane 33g Mass of CO2 176.04g <- This is wrong and the right answer is 99g CO2 How is that so. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. What mass of butane in grams is necessary to produce 1.5 x 103 kJ of heat What mass of CO2 is produced C4H10 + 13/2 O2 -> 4 CO2 + 5 H2O Heat of reaction -2658 kJ 2.(1 u is equal to 1/12 the mass of one atom of carbon-12) Therefore, other gases should have higher molar mass to balance butaneвЂ™s molar mass of 58 g/mole to 66.6 g/mole. Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). The calculated molar mass of the gas should have the average molar mass of the entire gas, including butane.To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Д®xamples of molecular weight computations:Дefinitions of molecular mass, molecular weight, molar mass and molar weight 1.3 milliliters of butane 0.779 gram: 1.4 milliliters of butane 0.839 gram: 1 1 / 2 milliliters of butane 0.899 gram: 1.6 milliliters of butane 0.959 gram: 1.7 milliliters of butane 1.02 grams: 1.8 milliliters of butane 1.08 grams: 1.9 milliliters of butane 1.

Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Д¬omputing molecular weight (molecular mass)
