How do you find how many atoms of an element are in a compound if you are only given the name and not the formula?

Draw the structure based on the name. Then count the number of times each atom appears in the structure. Alternately, you can determine the formula from the structure - and then count all atoms of each type.

Which two of Dalton's theory were incorrect?
These affirmations are not valid today:· All atoms of a given element are identical.· A given compound always has the same relative numbers of types of atoms.
What part Dalton atomic theory was later proved to be incorrect?
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
What information is given by a molecular formula?
the empirical formula and the molar mass
What did John Dalton get wrong?
Thse affirmations are not considered valid today:· All atoms of a given element are identical. · A given compound always has the same relative numbers of types of atoms.
what are the 4 points in Dalton's atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
What is the compound H22 O11?
The given compound does not exist if there are twelve carbon atoms before hydrogen atoms then it will be the formula for sugar.

What is the molecular formula of a compound given that molar mass of the compound is 30.04 gram and the empirical formula is NH?
The molecular formula of this compound is N2H2. This is obvious because the empirical formula of a compound is the lowest positive integer ratio of atoms present.
How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.
What is the formula for oxygen in chemical compounds?
Oxygen is always given the symbol O In chemical compounds there can be many oxygen atoms. The compound has the formula not oxygen. Example Water is the compound, its formula is H2O Sodium sulfate is the compound, its formula is H2SO4
What information is given by a molecular formula?
the empirical formula and the molar mass
What information is given by the formula of an ionic compound?
For an ionic compound, the name of the positive ion comes first, followed by the name of the negative ion. It also tells the ratio of the atoms and tells what atoms make up the compound.they describe the type and number of atoms in a molecule of the compound

How do you identify and kinds of atoms in a given compound based n its chemical formula?
The chemical formula is representative for a molecule and give indication about the chemical composition.
The subscripts of a compound indicate?
Subscripts after an element symbol indicate the number of atoms of that element in the compound, or (for more complicated compounds) in the particular radical in that part of the formula. For example, N with a subscript of 2 means 2 nitrogen atoms. If you wanted to indicate multiple numbers of a given radical or compound, that is indicated by a number on the line, rather than a subscript, and it comes before not after.
