Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.

While using the pH meter or taking the measurement using the pH meter --
- it should be kept in a storage solution for effective working.
- Before using the device, it is rinsed with a deionized water and pat dry.
- Record the measurements when the pH meter stabilizes.
It has two elements.
