Answer: The molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.
Explanation:
Given: 
= 43.6 mL, 
= 0.125 M
= 25.0 mL, 
= ?
Formula used to calculate the concentration of acid is as follows.
Substitute the values into above formula.
Thus, we can conclude that the molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.
Okay!
8.50molH, represents 8.50 moles of Hydrogen gas!
To convert from moles to volume multiply it by the ratio of L/molH
mol of anything in a conversion problem is always 1 unless you are going to an unknown! Try to memorize this, but the number you always put in for the # of liters in a conversion problem is 22.4L (L is a measure of volume)
8.50molH * (22.4 L/ 1 molH)
190.L of Hydrogen Gas.
Hope that helped!

I think you use sig figs in percent error.
Answer:
Ice
Explanation:
The Ice would absorb heat to change the temperature from anything below 1 degree celsius in order to become liquid water. After being a liquid water it'd absorb further amount of energy in order to increase it's temperature to 100 degrees. Therefore, the Ice absorb more water
The hydrogen one because who doesnt like snoballs'
