Molar mass is a whole number multiple of the a) empirical formula mass c) average atomic mass b) amu d) mass percent?
The correct answer is a) empirical formula mass. The molar mass of a compound is often a whole number multiple of its empirical formula mass, as the empirical formula represents the simplest whole-number ratio of the elements in the compound, while the molar mass reflects the total mass of a mole of its molecules or formula units.
What is the definition of empirical probability?
the ratio of the number favorable outcomes to the total number of trials.
All of the following are empirical formulas EXCEPT a) Fe(OH)3 c) N2O4 b) Na2SO4 d) Sn3(PO4)2?
The correct answer is c) N2O4. While N2O4 represents a molecular formula indicating the number of atoms in a molecule, the empirical formula would simplify it to NO2, which reflects the simplest whole-number ratio of the elements. The other options (Fe(OH)3, Na2SO4, and Sn3(PO4)2) are already in their simplest ratio forms, thus qualifying as empirical formulas.
What is another name for Experimental Probability?
Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.
What is the ratio of the number of times an event occurs to the total number of trial is called?
The ratio of the number of times an event occurs to the total number of trials is called the "empirical probability" or "experimental probability." It is calculated by dividing the number of successful outcomes by the total number of trials conducted. This ratio provides an estimate of the likelihood of the event based on observed data rather than theoretical calculations.
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
What the empirical formula for c12h12?
CH will be the empirical formula and C12H12 will be the molecular formula
How to calculate empirial formula from molecular formula?
To calculate the empirical formula from a molecular formula, divide the subscripts in the molecular formula by the greatest common factor to get the simplest ratio of atoms. This simplest ratio represents the empirical formula.
What is The smallest whole-number ratio of the element in an ionic or covalent bond?
The smallest whole-number ratio of elements in an ionic or covalent bond is determined by the lowest whole-number ratio of atoms present in the compound's chemical formula. For example, in water (H2O), the ratio of hydrogen to oxygen atoms is 2:1, hence the smallest whole-number ratio.
What is the empirical formula for C16H16N2O2?
The empirical formula for C16H16N2O2 is C8H8N. This formula represents the simplest whole-number ratio of the elements in the compound.
Is NH3 an empirical formula?
Yes, NH3 is an empirical formula. An empirical formula represents the simplest whole-number ratio of atoms in a compound. In the case of ammonia (NH3), the ratio of nitrogen to hydrogen is 1:3, making NH3 the empirical formula.
What is the empirical formula of C4H6?
The empirical formula of organic compounds is the lowest whole number ratio of atoms contained in the substance, as defined in chemistry. The empirical formula gives the minimal ratio of the number of various atoms that exist. It's an empirical formula, if the formula is shortened, but not the exact number of atoms in the molecule, C4H6 is the chemical formula for butane. For every mole of carbon, there are two moles of hydrogen. The carbon-to-hydrogen ratio equals 2:3. C2H3 is the empirical formula for butane (C4H6). Hence, the correct answer is C2H3.
What is the lowest whole number ratio of ions in an ionic compound called?
an empirical formula For an ionic compound, the empirical formula is called a formula unit.
What is the empirical formula for compound whose molecular formula is c2n2?
aromatic hydrocarbons
An empirical formula may not be the smallest whole number ratio of atoms in a compound true or false?
True. An empirical formula is the simplest whole number ratio of atoms in a compound, but it may not always be the smallest possible ratio. The molecular formula, which gives the exact number of atoms in a compound, may be a multiple of the empirical formula.
Do C6H12 and C6h14 have the same emoiricual formula?
No. The empirical formula of a substance is the formula in which each atomic symbol has the lowest possible subscript that gives the correct ratio between atoms for the compound as a whole. For C6H12, the empirical formula is CH2, but for C6H14, the empirical formula is C3H7.
What is Maltose's empirical formula?
Maltose's empirical formula is C12H22O11, which represents the simplest whole-number ratio of the elements present in the compound.
