A molecule of ethanol has 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom. Their atomic masses are 12, 1 and 16 in order. By adding of the masses, the molecular mass of ethanol is 12x2+1x6+16=46u.
The molar mass of humid air is approximately 28.97 grams per mole.
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
To calculate the number of moles in 42 grams of CO2, we first need to find the molar mass of CO2, which is approximately 44 grams per mole. Then, divide the given mass by the molar mass to find the number of moles. In this case, 42 grams of CO2 is equivalent to 42/44 = 0.955 moles.
To calculate the mass of CdS, we need to have the molar mass of CdS. Cadmium (Cd) has a molar mass of approximately 112.41 g/mol, and sulfur (S) has a molar mass of approximately 32.07 g/mol. Adding these together, we get a molar mass of approximately 144.48 g/mol for CdS. To find the mass of 2.50 x 10^-2 mol of CdS, we would multiply the number of moles by the molar mass: (2.50 x 10^-2 mol) x (144.48 g/mol) = 3.61 g of CdS.
To determine the number of moles, use the formula: moles = mass / molar mass. The molar mass of C2H5OH (ethanol) is approximately 46.07 g/mol. Therefore, 11.5g of C2H5OH represents approximately 0.25 moles.

For this you need the atomic (molecular) mass of C2H5OH. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. C2H5OH= 46.1 grams1.271 grams C2H5OH / (46.1 grams) = .0276 moles C2H5OH
The mass of 2 moles of ethyl alcohol would be 92,14 grams.
remember that mass divided by molecular mass = the number of moles the atomic mass' are as follows : C = 112.01 O = 16 H = 1.01 the molecular mass of a methanol molecule is that of 2 carbons 6 hydrogens and one oxygen = 46.08g following you divide 25g(measure of mass) by 46.08(atomic mass) = 10.54 mole. (the grams will cancel with each other leaving mole as the unit if you want to take a strictly mathmathical point of view)
To calculate the number of grams of C6H12O6 needed to form 7.50g of C2H5OH, you need to consider the stoichiometry of the reaction between these two compounds. The balanced equation for the conversion of C6H12O6 to C2H5OH is C6H12O6 -> 2 C2H5OH. This means that for every mole of C6H12O6, you get 2 moles of C2H5OH. You can then use the molar mass of each compound to convert grams to moles, and then determine the grams of C6H12O6 needed to form 7.50g of C2H5OH.
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The molar mass of glucose is 180,16 g.
what is the molar mass for NaC1 !!!???!!!???!!!??? --- The molar mass of sodium chloride (NaCl) is 57,958 622 382.
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
The molar mass of iron is 55.845g per mol. Molar mass is the mass of a given substance divided by its amount of substance.
