0.1324 ×10^24 atoms of carbon are in 2.65 g of carbon
Explanation:
Converting the grams of carbon to the moles of carbon.
Divide the mass (2.65 g) by 12.011 g/mol which is the molecular weight of carbon,
2.65 g / 12.011 g/mol=0.220 moles of carbon
Then, convert moles of carbon to atoms of carbon using Avogadro's constant (6.022×10^23 atoms per mole)
0.220 moles × 6.022×10^23 atoms / 1 mole = 0.1324 ×10^24 atoms
0.1324 ×10^24 atoms of carbon are in 2.65 g of carbon
Answer:True
Explanation:
A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.
Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.
Lets take A be the solute and B be the solvent so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).
The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.
The enthalpy of mixing and volume of mixing of ideal solution is zero.
enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case of ideal solutions it is zero.
Volume of mixing is change in volume on mixing a solute and solvent.
