How many molecules are there in 223 grams of Na2SO4?
Harlamova29_29 [7]
<h3><u>Answer;</u></h3>

= 9.45 × 10^23 molecules

<h3><u>Explanation; </u></h3>

The molar mass of Na2SO4 = 142.04 g/mol

Number of moles = mass/molar mass

                             = 223/142.04

                             =  1.57 moles

But;

1 mole = 6.02 × 10^23 molecules

Therefore;

1.57 moles = ?

= 1.57 × 6.02 × 10^23 molecules

<u>= 9.45 × 10^23 molecules </u>

Parts of a neuron include:<br> A. dendrites.<br> B. hormones.<br> C. cortexes.<br> D. collosums.
Tcecarenko [31]

The parts of the neuron include (A) dendrites.

<h3>What are dendrites?</h3>
  • Dendrites are appendages that are designed to receive communications from other cells.
  • They take the shape of projections with a tree-like structure that are triggered by other neurons and carry the electrochemical charge to the cell body.
  • These occupy a large surface area of a neuron.
  • These little appendages convey electrical stimulation to the soma and take in information from neighboring neurons.
  • Synapses are also found on dendrites.
  • Dendrites are also called the "arms" of a neuron.

As it is given in the description, Synapses are also found on dendrites.

Therefore, the parts of the neuron include (A) dendrites.
