Their weights could be different.
Their volumes could be different.
Their densities could be different.

The volume for an ounce of lead is much different than an ounce of aluminum.

the weight of a cubic meter of balsa wood is much different (and much lighter) than a cubic meter of water. That's why the ancients used balsa for their rafts.

Gallium (Ga) consists of two naturally occurring isotopes with masses of 68.926 and 70.925 amu. (a) How many protons and neutron

pav-90 [236]

Answer:

$neutrons_{Ga-69}=38\\\\neutrons_{Ga-71}=40$

Explanation:

Hello!

In this case, since isotopes of the same element have the same number of protons and electrons but different atomic mass, we can compute the number of neutrons by subtracting the number of protons to the atomic mass of the isotope; thus, for Ga-69 and Ga-71 (rounded up to whole numbers), we obtain:

$neutrons_{Ga-69}=69-31=38\\\\neutrons_{Ga-71}=71-31=40$

Best regards!
