The balanced equation for the acid base reaction is as follows
NaOH + HCl ---> NaCl + H₂O
stoichiometry of NaOH to HCl is 1:1
the number of NaOH moles reacted - 0.200 mol/L x 0.0250 L = 0.005 mol
according to molar ratio
number of NaOH moles reacted = number of HCl moles reacted 
therefore number of HCl moles - 0.005 mol 
volume of 30.0  mL contains 0.005 mol
therefore 1000 mL contains - 0.005 mol / 0.030 L = 0.167 M
concentration of HCl is 0.167 M

Matthew has been collecting quarters in a jar. He has 176 quarters. What is the value of the coins in his jar?
AURORKA [14]

Answer:

The correct answer is : 44 dollars.

Explanation:

A quarter is one fourth of a dollar that is the reason it is known as quarter. A quarter is 25 cents or 0.25 dollar in value. If Matthew has 176 quarters in his jar than the value of the total coins would be:

1 quarter = 0.25 dollar

1 quarter = 1/4 dollar.

4 quarter = 1 dollar

then, 176 / 4 = x dollar

 = 44 dollar

Thus, The correct answer is : 44 dollars.
