Answer : The mass defect required to release energy is 6111.111 kg
Explanation :
To calculate the mass defect for given energy released, we use Einstein's equation:
E = Energy released =
= mass change = ?
c = speed of light =
Now put all the given values in above equation, we get:
Therefore, the mass defect required to release energy is 6111.111 kg
[] value of soft drink is 0.0001mol/l when given pH is 4.
Given:
pH = 4
Needs to find: []
Formula to find: pH=−log [
]
We can put the values of pH in above formula as,
pH=−log [
]
4 =−log [
]
