The reaction is: HCl + Na HCO3 → NaCl + H2CO3, which is already balanced.
Then the molar ratios are 1 mol HCL : 1 mol NaHCO3
You know the mass of NaHCO3 is 0.100 g, then you can find the number of moles using the molar mass of NaHCO3
molar mass of NaHCO3 is 23 g/mol + 1 g/mol + 12g/mol + 3*16g/mol = 84 g/mol
And the number of moles is: 0,100 g / 84 g/mol = 0,0012 mol of NaHCO3.
Then, from the ratio 1:1, you know that, at the titration point, the number of moles of HCl is the same: 0,0012 mol of HCl.
Now from the fomula of molarity you have: M = #of moles / V in liters
=> V in liters = # of moles / M = 0.0012 mol / 0.100 M = 0.012 liters
Answer: 0.012 liters of HCL
Answer: 18.97 L
Explanation:
This can be solved by the Ideal Gas equation:
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
Finding :
Therefore:
The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is <u>18.97</u> liters
I think that the correct answer is fission
Answer:
It's (6.02214179×1023) / one mole of substance.
