How many moles of Ca atoms are in 1 mol of CaSO4?

Chemistry
1 answer:
N76 [4]2 years ago
3 0

Hey there!

There is 1 mol of Ca atoms in 1 mol of CaSO₄

There is one atom of Ca in each molecule of CaSO₄, so in 6.022 x 10²³ molecules of CaSO⁴ there will be 6.022 x 10²³ atoms of Ca.

Hope this helps!

Answer:

                       1.66 × 10⁻¹⁸  Moles

Explanation:

                     As we know one mole of any substance contains 6.022 × 10²³ particles (atoms, ions, molecules or formula units). This number is also called as Avogadro's Number.

The relation between Moles, Number of Atoms and Avogadro's Number is given as,

             Number of Moles  =  Number of Atoms ÷ 6.022 × 10²³ Atoms/mol

Putting values,

              Number of Moles  =  1.0 × 10⁶ Atoms ÷ 6.022 × 10²³ Atoms/mol

              Number of Moles  =  1.66 × 10⁻¹⁸  Moles

A voltaic cell has a zinc anode and a copper cathode. They are connected by a wire but no salt bridge. What can you predict will
Allisa [31]

The prediction is that B. The electrons will flow to the zinc anode where a negative charge will build up and eventually halt the reaction.

<h3>What is zinc?</h3>

This is known as a chemical element, of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance.

Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.

Hence, we know that the purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another.
