•You have 560. mL of aluminum hydroxide, with a molarity of 0.0300 M. When mixed with 871 mL of hydrochloric acid, what is the molarity (M) of the acidic solution?
•How many liters of 0.488 M H3PO4 are produced with 35.1 mL of 0.320 M of Ca(OH)2 ?

For 1: The molarity of acidic solution is 0.579 M

For 2: The volume of acidic solution is 0.0153 L

Explanation:

To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid

are the n-factor, molarity and volume of base

We are given:

Putting values in above equation, we get:

Hence, the molarity of acidic solution is 0.579 M

We are given:

Putting values in above equation, we get:

Hence, the volume of acidic solution is 0.0153 L

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
