What is the molecular formula of NH2Cl molar 51.5g?
The molar mass of NH2Cl is 51.5 g/mol, which means one mole of NH2Cl weighs 51.5 grams. The molecular formula of NH2Cl remains the same, NH2Cl, regardless of its molar mass.
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. Determine molecular formula and the accurate molar mass.?
A sample of a compound contain 1.52 g of Nitrogen and 3.47 g of Oxygen. The molar mass of this compound is between 90 grams and 95 grams. The molecular formula and the accurate molar mass would be N14O35.
What is the molecular formula of a compound that has an empirical formula of c2oh4 and a molar mass of 88 grams per mole?
The empirical formula C2OH4 simplifies to C1O2H2. To find the molecular formula, divide the molar mass (88 g/mol) by the empirical formula mass (112 + 216 + 2*1 = 46 g/mol) to get 1.91. This means the molecular formula is approximately 1.91 times the empirical formula, so the molecular formula is C2O4H4.
What is the molecular formula of the compound ch2 with molar mass equals 168 gmol?
c12h24
How can you find the molecular formula of a compound when its percentage composition is given?
Yes, if you have some additional information, such as the molecular weight. For instance, the molecules C2H4 and C4H8 have exactly the same percent composition, but they are very different molecules. So you need some other information to tell them apart than the percent composition.Answer ExpandedThis is kind of a trick question. By knowing the percent composition, you would easily be able to determine its empirical formula, but molecular formula is a bit different. The molecular formula is the actual number of atoms in a molecule, so in order to find the specific molecular formula of a substance, you would also need to know how many grams there is of that substance.(This explains the difference between C2H4 and C4H8)
What is the molecular formula of dicyclohexyl if its molar mass is 200 grams?
Dicyclohexyl chemical formula is C12H22 and the molecular weight is 166,3031 (not 200).
Is molar mass is mass in grams of one kilogram of any pure substance?
No, molar mass is the mass in grams of one mole of a substance. One mole is equal to the molecular weight of the substance in grams.
What is relationship between the formula weight of a substance and its molar mass?
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
The mass of a mole of a substance expressed in grams is called a?
The mass of a mole of a substance expressed in grams is called the molar mass. This value is numerically equal to the atomic or molecular weight of the substance and is expressed in units of grams per mole.
What is the molecular formula of MSG if molar mass is 169 grams?
The chemical formula of monosodium glutamate is C5H8NO4Na.
How does on determine a molecular formula from the empirical formula?
molar mass over grams of elementThe above answer is somewhat correct. In order to find the molecular formula when given the empirical formula, you must first find the molar mass of the empirical formula.MOLAR MASS# atoms element A x Atomic Mass element A (Periodic Table) = mass A# atoms element B x atomic mass element B (periodic table) = mass B... etc.Add up all of the mass values found above and you have the molar mass.Then, after you have found the empirical formula's molar mass, you divide the molar mass of the molecular formula by the empirical formula's molar mass (solving for n).MOLECULAR FORMULA EQUATION: N (Empirical formula) (read as N times empirical formula) where:N = Molar mass substance---- Molar Mass emp. form.
What terms is used to describe the mass in grams of 1 mol of a substance?
This ter is molecular (molar) mass.
What steps are used to convert an empirical formula into a molecular formula?
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
What is the molecular formula of NH2Cl molar 51.5g?
The molar mass of NH2Cl is 51.5 g/mol, which means one mole of NH2Cl weighs 51.5 grams. The molecular formula of NH2Cl remains the same, NH2Cl, regardless of its molar mass.
What is the molar mass of a substance?
The molecular weight (or, more appropriately, the molar mass) is defined by # of grams per # of moles. MW = g / mol For example: if you have 4 grams of substance and you know the substance to be 2 moles (say, for example, the balanced chemical equation), then your MW would be 2.
How do calculate how many mole are in grams?
For these conversions, you need the atomic masses of the elements involved in grams. If it is just one element, then you use the atomic mass, but if its a compound, then use the molecular mass (added atomic masses). Take the number of moles and multiply it by the atomic (molecular) mass to get number of grams.
