What is the molecular formula of a compound with an empirical formula of C4H9 and a gram formula mass of 114 grams mole?

To determine the molecular formula from the empirical formula and gram formula mass, first calculate the empirical formula mass of C4H9 (4 carbons + 9 hydrogens). Then, divide the gram formula mass by the empirical formula mass to find the ratio. Finally, multiply the subscripts in the empirical formula by this ratio to get the molecular formula, which in this case is C8H18.


The gram-formula mass of no2 is defined as the mass of?

The gram-formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit of the compound. For NO2, the gram-formula mass is calculated by adding the atomic mass of nitrogen (N) and two times the atomic mass of oxygen (O).

How many moles of water are on 72.08g of H2O?

The molecular formula of water is H2O. The atomic mass of H2O is 2(1.0) + 16.0 = 18.0Amount of H2O = mass of pure sample/molar mass = 75/18.0 = 4.17mol There are 4.17 moles of water in a 75 gram pure sample.


How many moles are in 1 gram of H2O?

There is approximately 0.055 moles of water (H2O) in 1 gram. This can be calculated by dividing the given mass (1 gram) by the molar mass of water (18 grams/mol).


Why can't a substance have an empirical formula of NO and a gram formula mass of 45g?

From the Periodic Table The Atomic mass of Nitrogen (N) is 14 The Atomic mass of Oxygen (O) is 16 Hence the gram formula mass of NO is 14 + 16 = 30 Now NO under certain circumstances can form N2O2 hence the gram formula mass of N2O2 = (2 x 14) + ( 2 x 16) = 28 + 32 = 60 However the empirical formula is the formula with the lowest ratio of atoms. Hence N2O2 lowest ration is NO # formula mass is 30 .
