How much heat would be developed per hour form 1 curie of `C^(14)` source, if all the energy of beta decay were imprisoned? Atomic masses of `C^(14)` and `N^(14)` are `14.00324` absd `14.00307` amu respectively.

Mention the mass of ""^(14)N -atom in amu.

Calculate the number of electrons in 1.4 gram 7^(N^(3-)) ion. (Atomic mass of N=14).

What is the mass of one atom of C(atomic mass 14)

Calculate the percentage of nitrogen in NH_3 (Atomic mass of N = 14, H = 1amu)

Calculate the percentage of nitrogens in NH_(3) . (Atomic mass of N=14, H=1 amu)

How many protons and neutrons are present in the nuclei of C^14 and N^14 isotopes ?

What is the percentage of carbon in urea? (Atomic mass C = 12, H = 1, N = 14, O = 16)

The relative abundance of three isotopes of carbon C^(12), C^(13) and C^14 are 98.892%, 1.108% and 2 xx 10^(-10) % respectively. If the relative atomic masses of these isotopes are 12.00, 13.00335 and 14.00317 amu respectively, find the average atomic mass of carbon.
