The question is incomplete, here is the complete question:
What volume (mL) of the partially neutralized stomach acid having concentration 2 M was neutralized by 0.1 M NaOH during the titration? (portion of 25.00 mL NaOH sample was used; this was the HCl remaining after the antacid tablet did it's job)
<u>Answer:</u> The volume of HCl neutralized is 1.25 mL
<u>Explanation:</u>
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of stomach acid which is HCl
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the volume of HCl neutralized is 1.25 mL
Answer:False, we can sense four tastes, namely salty, sweet, sour and bitter. Acids taste sour. If we want to know if something is an acid, we can just taste it.

Answer:
0.91 g NaF
Explanation:
Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100%.
Let mass of NaF = x g
∴ mass percent = mass of NaF / mass of total mixture *100
3.5 = (x/ x + 25) * 100
∴ x = 0.91 g
Answer:
The answer is 79.904.
