Answer:
Molarity of solution is 0.0928 M.
Explanation:
Balanced equation:
Number of moles of in 10.8 mL of 0.0215 M solution
= = 0.000232 moles
Let's assume molarity of solution is S(M)
Number of moles of in 12.50 mL of S(M) solution
= = 0.0125S moles
According to balanced equation, 5 moles of react with 1 mol of
So, 0.0125S moles of react with moles of
Hence,
or, S = 0.0928
So, molarity of solution is 0.0928 M.
Answer:
Standard boiling point
Explanation:
Note that there are 2 major units of pressure except Pa .
- bar
- atm
At 1 atm pressure the boiling temperature is called normal boiling point.
At 1 bar pressure the boiling temperature is called standard boiling point
0.761 mol of would you have if you have 76.36 grams.
<h3>What is a mole?</h3>
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Mass=76.36 grams
Moles = 0.761
Hence, 0.761 mol of would you have if you have 76.36 grams.

Answer: A
0 degrees and 101 kPa are the conditions that describe the standard temperature and pressure. When expressed in K, the standard temperature 0 degrees equals 273.5 K. Also the standard pressure 101 kPa equals 760 mmHg or 1 Atm.
