Answer:
Molar mass of the metal = 59.0 g/mol
Explanation:
Vapor pressure of water at = 23.78 torr
We are given:
Total vapor pressure = 756.0 torr
Vapor pressure of hydrogen gas = Total vapor pressure - Vapor pressure of water = (756.0 - 23.78) torr = 732.22 torr
To calculate the amount of hydrogen gas collected, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 732.22 torr
V = Volume of the gas = 255 mL = 0.255 L ( 1 mL = 0.001 L )
T = Temperature of the gas =
R = Gas constant =
n = number of moles of hydrogen gas = ?
Putting values in above equation, we get:
From the reaction shown below:-
1 mole of hydrogen gas is produced when 1 mole of the metal is reacted.
Also,
0.01 mole of hydrogen gas is produced when 0.01 mole of the metal is reacted.
Moles of the metal = 0.01 mol
Mass taken = 0.590 g
The formula for the calculation of moles is shown below:
Thus,
Molar mass of the metal = 59.0 g/mol
Answer: The formula of the acid that was neutralized is
Explanation:
Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate and bases donate
in water which combine to form water molecules.
As the salt formed is , the acid must contain
and thus the acid is
The balanced chemical reaction is ;
The formula of the acid that was neutralized is
