What is the empirical formula of a compound composed of 31.1 g potassium and 6.36 g oxygen?
CH3 is the empirical formula of C2H6; this molecule is an alkane commonly known as ethane.
a certain carbohydrate contains three elements carbon, hydrogen, and oxygen. the combustion of 59.5 g of sample produces 103.9 g of co2 and 8.50 g of h2o what is the empirical formula?
C2.5 H1 O2
2g sample of a sugar determined that it contain 0.8g carbon 0.13g hydrogen with the remainder being oxygendetermine the empirical formula of sugar?
There are then 1.07 grams of oxygen in the sample (1.07 + .13 + .8 = 2.0). Carbon has a molar mass of 6, oxygen is 8 and hydrogen is 1. This gives the molar ration of C:H:O at about 0.8/6:0.13/1:1.07/8, reduced to .13:.13:.13. Thus the empirical formula is CHO.
A 2.144-g sample of phosgene a compound used as a chemical warfare agent during World War 1 contains 0.260 g of carbon 0.347 g of oxygen and 1.537 g of chlorine. What is the empirical formula of this?
moles C = 0.260 g C x 1 mol/12 g = 0.0217 moles Cmoles O = 0.347 g O x 1 mol/16 g = 0.0217 moles Omoles Cl = 1.537 g Cl x 1 mol/35.5 g = 0.043 moles Clmole ratio = 1C : 1O : 2Cl so empirical formula = COCl2
Which sample contains the greatest number of atoms a sample of Mn that contains 3.29E plus 24 atoms or a 5.18 mole sample of you?
Which sample contains the greatest number of atoms. A sample of Mn that contains 3.29E+24 atoms or a 5.18 mole sample of I?The sample of _____ contains the greatest number of atoms.Answer:In order to compare the two samples, it is necessary to express both quantities in the same units. Since the question was phrased in terms of atoms, it is convenient to convert moles of I to atoms of I.The conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / molTo convert 5.18 moles of I to atoms of I:atoms I= 5.18 mol I6.02 x 1023 atoms I = 3.12E+24 atoms I1 mol IMultiply by atoms per mole. Moles cancel out.The sample of Mn contains 3.29E+24 atoms.Since 3.12E+24 is smaller than 3.29E+24, the sample of Mn contains the greatest number of atoms.
Determine the empirical formula what compound if a sample contains 0.104 mol K 0.052 mol C and 0.156 mol O?
Kc2o4
Determine the empirical formula of the following compound if a sample contains 5.28g Sn and 3.37g F?
get grams to moles, then divide each mol by the smallest mol. in htis case, you'd get, F4Sn.
What is the empirical formula for a compound if a 20.0 g sample contains 4.0 g Ca and 16.0 g Br?

2g sample of a sugar determined that it contain 0.8g carbon 0.13g hydrogen with the remainder being oxygendetermine the empirical formula of sugar?
There are then 1.07 grams of oxygen in the sample (1.07 + .13 + .8 = 2.0). Carbon has a molar mass of 6, oxygen is 8 and hydrogen is 1. This gives the molar ration of C:H:O at about 0.8/6:0.13/1:1.07/8, reduced to .13:.13:.13. Thus the empirical formula is CHO.
