The volume of the solution is given below which can be calculated using the molarity formula as 2.18 litres.
<h3>Define the molarity of a solution.</h3>Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution.
Given data:
M= 0.420M
mass = 64.0 grams
Molar Mass= 74g/mol
To find:
The volume of solution=?
The calculation for a number of moles:
n=
n=
n= 0.91 moles
Molarity=
V=
V= 2.1768 litres
Thus, the volume of the solution is 2.18 litres.

Answer:
The most reasonable estimate for the O–S–O bond angle in hyposulfite = 106°
Explanation:
Hyposulphite (so₂²⁻) is polyatomic ion .
According to VSEPR model
Total elrctron pairs
V = Valence shell electrons of central element
X = No. of monovalent surrounding atoms
C = Cationic charge
A = Anionic charge
Total electron pairs
That is two bond pairs and two lone pairs
<u>Answer:</u> The boiling point of water in Tibet is 69.9°C
<u>Explanation:</u>
To calculate the boiling point of water in Tibet, we use the Clausius-Clayperon equation, which is:
where,
= initial pressure which is the pressure at normal boiling point = 1 atm = 760 mmHg (Conversion factor: 1 atm = 760 mmHg)
= final pressure = 240. mmHg
= Heat of vaporization = 40.7 kJ/mol = 40700 J/mol (Conversion factor: 1 kJ = 1000 J)
R = Gas constant = 8.314 J/mol K
= initial temperature or normal boiling point of water =
= final temperature = ?
Putting values in above equation, we get:
Converting the temperature from kelvins to degree Celsius, by using the conversion factor:
Hence, the boiling point of water in Tibet is 69.9°C
