empirical formula or molecular formula
What are the sum of atomic masses of all atoms formula for a compound called?
It is called the molar mass of that compound. In other words, the total mass of all of the elements in a compound is equal to one mole of that compound.
What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
Is AgNO3 a compound or element?
A compound: any formula that contains more than one kind of atomic symbols represents a compound.
How do you ionize a compound?
Add or take out an electron so that the atomic charge is unbalanced to get an ion.

empirical formula or molecular formula
A glucose molecule contains carbon hydrogen and oxygen in the ratio 6 to 12 to 6 What is the molecular formula for glucose?
Molecular formulas can not be determined from information about atomic ratios only. If the ratios stated are atomic ratios, then the empirical formula of the compound is CH2O. If the questioner meant, "A glucose molecule contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms ...", the molecular formula is C6H12O6.

It is called the molar mass of that compound. In other words, the total mass of all of the elements in a compound is equal to one mole of that compound.
What is the sum of the atomic masses of all the atoms in a molecule?
molecular mass
What is the formula for the percent by mass of a compound?
((mass of element)/(mass of compound))*100
What is the molecular formula for sodium hydroxide?
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
A compound with the empirical formula SN was found in a subsequent experiment to have a molar mass of 184.32 gmol. What is the molecular formula of the compound?
The empirical formula of SN has a formula unit mass of the sum of the gram atomic masses of nitrogen and sulfur, i.e., about 46.0667. The gram molecular mass given in the problem divided by this formula unit mass is about 4. Therefore, the molecular formula is S4N4.
What is the molecular formula of the compound CH2 with molar mass 42.0?
The unit CH2 has a gram atomic mass of 12.011 + 2(1.00794) or about 14. 42.0/14 = 3; therefore the molecular formula is C3H3.
The molecular formula mass of this compound is 210 amu What are the subscripts in the actual molecular formula Enter the subscripts for C H and O?
Element Element's atomic massC : 12H2 : 2(hydrogen's atomic mass is 1 but remember there are two)O : 16Add all the elements atomic mass and then divide the molecular mass by it. After that you only need to multiply all the subscripts of each element to find your answer.12+2+16=30240/30=88(CH2O) = C8H16O8
Is atomic oxygen as molecular compound?
oxygen is an element not a molecular compound as a molecular compounds are chemically combined and are of more then one element.
What information is given by a molecular formula?
the empirical formula and the molar mass
What is the empirical formula of a compound that contains 43.38 sodium 11.33 carbon and 45.29 oxygen?
