In Chemistry:

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.

Ores are a mixture of minerals: processed to produce an industrial mineral or chemically treated to produce one or more metals. The steel, aluminum, chromium, zinc, mercury, manganese, tungsten, and some copper ores are typically processed for just one element.

How many moles of copper are present in 75.0g Cu? Show your complete calculation and give the answer in the correct number of si
velikii [3]

Answer:

The answer to your question is 1.2 moles of copper

Explanation:

Data

mass of copper = 75 g

moles = ?

Process

1.- Look in the periodic table for the atomic mass of copper.

Atomic mass = 63.55 g/mol

2.- Use proportions to determine the moles of copper in 75 g

                          63.55 g of copper -------------------- 1 mol

                          75 g of copper       --------------------  x

Use cross multiplication

                          x = (75 x 1) / 63.55

                          x = 75 / 63.55

                          x = 1.18 moles ≈ 1.2 moles of copper

Why does a solution of NaOH have to be standardized against a primary standard as supposed to just using the mass and volume to
Rudik [331]

NaOH is hygroscopic

Explanation:

  • A standard solution is a solution of known molarity or concentration.
  • Standard solutions are used in determining the stoichiometric amount of desired species in an experiment.
  • A solution of NaOH is not a standard solution because NaOH is hygroscopic in nature.
  • By this, NaOH absorbs moisture from the atmosphere in considerable amount.
  • This implies that one must find an air free environment to store and use the compound and accurately quantify it.
  • This is why a solution of NaOH is standardize with a primary standard.
