How many sodium ions are in 1.4 kg of sodium chloride, NaCl?
Whitepunk [10]

Answer:

1.44 x 10²⁵ ions of Na⁺

Explanation:

Given parameters:

Mass of NaCl  = 1.4kg  = 1400g

Unknown:

Number of ions of sodium  = ?

Solution:

The compound NaCl in ionic form can be written as;

      NaCl →  Na⁺ + Cl⁻

In 1 mole of NaCl we have 1 mole of sodium ions

 Now, let us find the number of moles in NaCl;

  Number of moles  = \frac{mass}{molar mass}  

    Molar mass of NaCl  = 23 + 35.5 = 58.5g/mol

Number of moles  =  \frac{1400}{58.5}     = 23.93mol

 So;

   Since 1 mole of NaCl gives 1 mole of Na⁺  

    In 23.93 mole of NaCl will give 23.93 mole of Na⁺

1 mole of a substance  = 6.02 x 10²³ ions of a substance

  23.93 mole of a substance  =  6.02 x 10²³ x  23.93

                                                   = 1.44 x 10²⁵ ions of Na⁺

Why do cells use fat and starch for long term energy storage instead of ATP molescules?
IceJOKER [234]
ADP is like an uncharged battery. ATP is like a charged battery, ready to provide energy to do work in the cell. The charging of ADP into ATP takes place in the mitochondria. Fat and starch are stable (last a long time) whereas ATP goes dead too quick and will need to be recharged.

glucose is a carbon chain molecule (sugar). When the bonds in the chain are broken, energy is released. That energy is used to turn ADP into ATP. Glucose is the "electricity" used to charge the battery.
