Answer:
The mass of 2.0 mol of C02 is 44 grams
Explanation:
The weight of CO2 is 44 grams per mole (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms)
Answer:
Graphite is an electrical conductor, hence useful in such applications as arc lamp electrodes. It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity.
Answer:
The "unit" remaining after conversion is atoms.
This is a way to calculate the number of atoms, in an specific mass.
Explanation:
When you have a mass, multiplying the molar mass, "grams" are cancelled, so you finally obtained, number of moles.
Moles . atoms/mol, cancel the word mol so you will find out a number of atoms, present at the mass from, the begining.
For example, how many atoms are in 10 g of NaCl
Molar mass NaCl = Na mass + Cl mass
23 + 35.45 = 58.45 g/m
10 g . 1 / 58.45 mol/g . NA/ 1 mol = 3.42x10²⁰ atoms
NA = Avogadro number
