What are the steps needed to covert 22 grams of copper to atoms of copper

Explanation:

Mole = No. Of atom/Avogadro const

Avogadro constant= 6.02×10^23

Mass of Cu =22g

Molar mass of Cu =63.5g/mol

Mole = mass/molar mass

Mole = 22/63.5

Mole = 0.346

No. Of atom=mloe ×avogadro conts

No. Of atom = 0.346 × 6.02×10^23

No. Of atom = 2.09 × 10^23atoms

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
