If 10.28 g of Cu(NO3)2 are obtained from the reaction of 4.54 g of Cu with excess HNO3, what is the percent yield of the reaction? (show workings for full grade)

The percent yield of the reaction : 77.2%

Percent yield is the comparison of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

Cu + 4HNO₃ → Cu(NO₃)₂ + 2NO₂ + 2H₂O

mol of Cu(MW=63.55 g/mol) :

mol ratio Cu : Cu(NO₃)₂ = 1 : 1, so mol Cu(NO₃)₂ :

mass of Cu(NO₃)₂ (MW=187,56 g/mol) :

10.28 g of Cu(NO₃)₂ are obtained from the reaction⇒actual yield

The percent yield :

the volume increases

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
