How many moles are in 42 grams of CO2?
just short of a mole. moles is mass/molar mass. mass is 42, molar mass is 44. 42/44
What is the mass in grams in 1.00 molar mass FE?
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
How do you convert from number of particles to moles?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
How do you find the mass of an atom with only the molar mass given?
Molar mass of an element is the atomic weight on the periodic table in grams. 1 mole of atoms of an element is 6.022 x 1023 atoms. To find the mass of one atom of an element, divide the element's molar mass by 6.022 x 1023 atoms.Example:Sodium, Na, has a molar mass of 22.989770g/mol (atomic weight in grams)1 mole Na atoms = 6.022 x 1023 atomsSolution:22.989770g/mol x 1mol/6.022 x 1023 atoms = 3.818 x 10-23g/atom
Which mathematical relationship should you use to convert moles of a substance into grams?
Multiplication by what is called a conversion factor. A moles x (bbb grams / 1 mole) in which bbb is the molar mass of the substance.
