What is the atomic weight in grams per mole of the element?
The atomic weight in grams per mole of an element is the average mass of one mole of atoms of that element, measured in grams.
How much matter is in uranium?
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
How can the weight of one mole of a substance be determined by looking at the periodic table?
The weight of one mole of an element is the element's atomic mass. So Carbon for example has an atomic mass of 12. If you had one mole of Carbon you would have 12 grams of Carbon.
Are there two moles in CH4?
That's a tricky question, because one molecule of CH4 is simply that, one atom of carbon and 4 atoms of Hydrogen. Moles are a UNIT used to transform atoms (which we cannot measure individually in the lab) into practical units such as grams (which we can measure). The moles of CH4 depend on the mass, in SI units of grams, that you have of this substance. The molecular weight of CH4 is 16 g/mol (12 for Carbon + 1 for each Hydrogen). If you WANTED 2 moles of CH4, you need to multiply this molecular weight by 2 moles to get 32 grams (the moles cancel out upon multiplication). So, 32 grams of CH4 is 2 moles of CH4.
What is the values represents the number of carbon atoms in one mole of methane?
elements and compounds.atom or atomic structure
What does the atomic mass of an element indicate?
The average weight in grams of one mole of the element.
One mole of boron has a mass of how many grams?
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
What is one gram in atomic weight?
the units for atomic weight are grams per mole. your question cannot really be answered correctly.
How many moles of carbon dioxide is formed when 44mol of CH4 is burned?
The equation for a complete combustion reaction of CH4 is : CH4 + 2 O2 = CO2 + 2 H2O, showing that one mole of carbon dioxide is formed for each mole of CH4 burned. Therefore, the answer is 44 moles of CO2 formed.
How many grams of CO2 are formed for every gram of CH4 that combusts?
The balanced equation for combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2OThus, one mole CH4 produces 1 mole CO21 g CH4 x 1 mole CH4/16 g = 0.0625 moles CH40.0625 moles CH4 ==> 0.0625 moles CO20.0625 moles CO2 x 44 g CO2/mole = 2.75 g CO2Thus, the answer would be that 1 grams of CH4 will produce 2.75 grams of CO2 after complete combustion.
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
How do you calculate a mole of an atoms weight in grams?
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.
