[
] value of soft drink is 0.0001mol/l when given pH is 4.
Given:
pH = 4
Needs to find: []
Formula to find: pH=−log
[]
We can put the values of pH in above formula as,
pH=−log []
4 =−log []

Answer:
The volume is 10,92 L
Explanation:
We use the formula PV=nRT:
V= (nRT)/P
V= (0,500 mol x 0,082 l atm/K mol x 799 K)/3,00 atm
<em>V= 10,91966667 L</em>
Covalent bonds are formed between nonmetals.
