Answer:5 carbons
Explanation:
Pentane is an organic compound with the formula C5H12—that is, an alkane with five carbon atoms.
They are both ionic compounds
A chemical reaction happens if you mix together an acid and a base. The reaction is called neutralisation<span>, and a neutral solution is made if you add just the right amount of acid and base together.</span>
The molarity of the solution : 1.2 M
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
mass of NaCl=35 g
Volume of solution = 0.5 L
mol NaCl(MW=58.44 g/mol) :
The molarity :
