['In methane there are only 2 elements, Carbon and Hydrogen.', 'The total mass of a methane molecule (CH4) is.', '4 x 1 + 12 = 16.', '%mass of H in methane= 4/16 x 100% = 25% %mass of C in methane = 12/16 x 100% = 75%']

Example 1: mass percent = (mass of chemical/total mass of compound) x 100 = (5 g/105 g) x 100. Example 2: We want to rearrange the mass percent equation to solve for the unknown mass of the chemical: mass of the chemical = (mass percent*total mass of the compound)/100 = (15*175)/100.

Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.

The percentage by mass or mass percentage is equal to the mass of the element divided by the mass of the sample all multiplied by 100 percent. In this case, the sample is one molecule of ethanol. And the mass of the element is the mass of either two carbon atoms, six hydrogen atoms, or one oxygen atom.

The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O.

The molar mass of the hydrate is the molar mass of the CoCl2 plus the mass of water. Calculate the percent by mass of water by dividing the mass of H2O in 1 mole of the hydrate by the molar mass of the hydrate and multiplying by 100%. Step 2: Calculate.

Start with the number of grams of each element, given in the problem. the mass of each element = the percent given. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated.

Calculate the mass percent by dividing the mass of the solute after evaporation by the mass of the initial solution.

The first step here is to determine the mass of C in CO2 and the mass of H in H2O. This is done by dividing the atomic mass by the molecular mass and then multiplying by the mass of compound produced. We therefore have a ratio of 1 carbon atom to 3 hydrogen atoms, thus the empirical formula for this hydrocarbon is CH3.

Therms and Mcf of natural gas Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12).

It is important to note that we can calculate the mass percentage composition by dividing the mass of a component by the total mass of the mixture. This ratio is then to be multiplied by 100. We also call it the mass percent(w/w) %.

This is the total weight of CO2. Now, to know the percent composition of Carbon and Oxygen . We will divide their weight with the total weight of CO2. % C = 12.01/44.01 = 0.2729= 27.29% (we will divide 0.2729 with 100 to take the percentage).

CH4+2O2======>CO2+2H20. So 1 mole of methane requires 2 moles of oxygen for complete combustion. So 16 g of Methane requires 64 g of oxygen for the complete combustion. So 8 g of Methane requires = 8x64/16=32 g of oxygen.
