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
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
What compound and elements are in MgS?
The name of the compound with this formula is "magnesium sulfide".
What is the empirical formula for a Compound with the molecular formula C16H12CI2O2?
The formula as written, including a capital "I", is already an empirical formula, since it shows a total of 7 carbon atoms and none of the other subscripts is integrally divisible by 7. However, the formula may have been intended to be written C16H12Cl2O2. In that instance, all the subscripts can be integrally divided by 2 to given an empirical formula of C8H6ClO.
Is CaMgCO a element or a compound?
It would be a compound. An element's symbol never has more than three letters and never has more than one uppercase letter. Note, though that no compound with this formula exists. You must remember your subscripts. The correct formula is CaMg(CO3)2, the formula for the mineral dolomite.

A notion that shows what elements a compound contains and the ratio of the atoms or ions of these elements in the compound?
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
What information is needed to calculate the percent composition of a compound?
The formula of the compound and the Atomic Mass of its elements.
The chemical formula of a compound does not indicate?
The chemical formula of a compound does not indicate the way that elements are joined in the compound. Chemical formulas tell you the identity of the elements in the compound and the relative proportions of the elements.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts
Why does oxygen not have a subscript?
Oxygen does not have a subscript since it is an element. Subscripts are usually found in the chemical formula of a compound and not an element.
