What is the atomic number for CHCOCH3?
take the atomic number of Carbon, Hydrogen, and Oxygen and add them up. Molar Mass.
What is the atomic number and atomic mass of alcohol?
Alcohol does not have an atomic number because it is not an element. Its molar mass is 46.07 g mol−1.
How is the molar mass of an element related to average atomic mass?
Molar mass is the weight of one mole of any chemical compounds. Atomic mass is the weight of just 1 atom of a compound
What is the relationship between the molar mass and atomic mass?
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams.The atomic mass is the mass of an isotope expressed in unified mass atomic units.The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
What is the molar mass of Te?
The molar mass of H2Te = 129.61588 g/mol
What is relationship between the formula weight of a substance and its molar mass?
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
What does the number above the symbol represent?
The atomic number.
Is avogadro's number the same as molar mass?
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
What is the atomic number for CHCOCH3?
take the atomic number of Carbon, Hydrogen, and Oxygen and add them up. Molar Mass.
What is the atomic number and atomic mass of alcohol?
Alcohol does not have an atomic number because it is not an element. Its molar mass is 46.07 g mol−1.
What are the molar conversions between moles and representative particles?
avagadros number
What is molar atomic mass?
The atomic (molecular) weight of a substance is its molar mass.
What are the steps for calculating molar mass of compound?
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
How is the molar mass of an element related to average atomic mass?
Molar mass is the weight of one mole of any chemical compounds. Atomic mass is the weight of just 1 atom of a compound
How do you convert from number of particles to moles?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
Is the atomic mass equal to the molar mass?
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
