Propose a reason why very few 2+ ions are formed in a mass spectrometer

Chemistry
1 answer:
TEA [102]3 years ago
5 0
A mass spectrometer is a machine that measures the mass of different substances by ionizing them and determining their paths in magnetic and electric fields. Few 2+ ions are created in a mass spectrometer because it is difficult to remove an electron from an ion that is already positive. It requires a lot more energy to accomplish this feat so it rarely happens in the process.

A solution of NaOH is titrated with H2SO4. It is found that 20.05 mL of 0.3564 M H2SO4 solution is equivalent to 43.42 mL of NaO
Darya [45]

Answer : The concentration of NaOH is, 0.336 M

Explanation:

To calculate the concentration of base, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=2\\M_1=0.3564M\\V_1=20.05mL\\n_2=1\\M_2=?\\V_2=43.42mL

Putting values in above equation, we get:

2\times 0.3564M\times 20.05mL=1\times M_2\times 43.42mL

M_2=0.336M

Thus, the concentration of NaOH is, 0.336 M
