How many atoms are in C13H18O2?
There are 33 atoms in that molecular formula. C13H18O2 (the molecular formula for Ibuprofen) has 13 carbon atoms, 18 hydrogen atoms, and 2 oxygen atoms.
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?
Given the molecular formula mass of 210 amu, the subscripts for C, H, and O in the actual molecular formula can be determined as follows: the atomic mass of carbon (C) is 12 amu the atomic mass of hydrogen (H) is 1 amu the atomic mass of oxygen (O) is 16 amu Thus, the subscripts for C, H, and O are calculated as follows: Subscript for C: 210 amu / 12 amu = 17.5 (approx. 18) Subscript for H: 210 amu / 1 amu = 210 Subscript for O: The compound doesn't contain oxygen since the sum of 18 (C) and 210 (H) exceeds 210, which is the given molecular formula mass.
What is the carbon content of kerosene?
Kerosene is comprised of multiple types of alkane (hydrocarbon) chains. These chains can vary between 6 to 18 carbons long. Cycloalkanes and aromatics (benzenes) are among kerosene's hydrocarbon constituents.
If 44 grams of carbon react completely with 18 grams of water what is the mass of carbonic acid formed?
The molecular formula for carbonic acid is H2CO3. To find the mass of carbonic acid formed, first calculate the moles of carbon and water. Then, determine the limiting reactant and use it to calculate the moles of carbonic acid formed. Finally, convert the moles of carbonic acid to grams to find the mass.
What is the molecular formula of peptone?
peptone water is used as a growth medium and as a carbohydrate fermentation media. peptic digest of animal tissue(peptone) = 10.0 gm/ltr NaCl= 5.0 gm/ltr water = 1000 ml ph( at 25 degree centigrade ) = 7.2 incubation period & temp. = 35-37 C. for 18-24 hrs
Is octane an ionic compound?
No, octane is not an ionic compound. Octane is a hydrocarbon, specifically an alkane, which consists of carbon and hydrogen atoms bonded together through covalent bonds. Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal.
Is C8H18 a alkane?
an Alkene as it contains a double bond and is unsaturated
How many atoms are in C13H18O2?
There are 33 atoms in that molecular formula. C13H18O2 (the molecular formula for Ibuprofen) has 13 carbon atoms, 18 hydrogen atoms, and 2 oxygen atoms.
What elements make up the compound C8H18?
The compound C8H18 is composed of carbon and hydrogen atoms. It is an alkane known as octane, with 8 carbon atoms and 18 hydrogen atoms in its chemical structure.
What is the molecular formula for argon?
Argon is an element, not a molecule, and as such does not have a molecular formula, but rather a symbol - "Ar".
What elements make up octane?
Hydrogen and Carbon ONLY. The formulka for octane is CH3CH2CH2CH2CH2CH2CH2CH3 As the name suggests from its Latin root. 'Octa' Eight carbons. and 'ane' a single bond (Alkane) functional group.
Which alkanes are solids at room temperature?
alkane is CnH2n+2. and any alkane with n= 18 and n>18 is solide. such as paraffin wax C18H38.
Which product has the largest molecular mass sodium acetate water or carbon dioxide?
Sodium acetate has a larger molecular mass than water or carbon dioxide. Water has a molecular mass of 18 g/mol, carbon dioxide has a molecular mass of 44 g/mol, and sodium acetate has a molecular mass of 82 g/mol.
which of the following is the correct model of C8H18?
just took the test
What is the combination of letters and numbers used to represent a substance?
A molecular formula contains the atomic composition by element and their quantities. For example H2O is the molecular formula for water. The formula indicates that there are two atoms of hydrogen (H) and one oxygen (O) in each water molecule. Through the molecular formula molar mass can further be derived. In the case of water is 18-grams per mole.
What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?
8 is not the answer because octane does no refer to the number of hydrogens but rather the number of carbons. c-c-c-c-c-c-c-c as you can see the number of hydrogens that would bond to the carbons is 18.-------The chemical formula of octane is C8H18, consequently the number of carbon atoms is 8.
How many total atoms are found in ibuprofen?
The molecular formula of ibuprofen is C₁₃H₁₈O₂. To calculate the total number of atoms, add the number of carbon, hydrogen, and oxygen atoms: 13 carbon atoms + 18 hydrogen atoms + 2 oxygen atoms = 33 atoms in ibuprofen.
