An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3. what is the estimated mass of the atom.

The estimated mass of the atom is 70 amu

Explanation:

An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3.      

Mass of an atom is equal to the sum of number of protons and number of neutrons.

In this case, number of protons p = 35

Number of neutron n = 35

So, the estimated mass of the atom will be :

Hence, this is the required solution.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
