<span>The question says.'which option describes a similarity between isotopes of an element. The correct option is C. Isotopes have the same number of atomic number but different mass number. The mass number is the summation of proton and neutron. The number of proton is always constant but that of neutron changes to reflect the existence of isotopes.</span>
molarity =Number of moles of compound*1000/(mass of solvent)
Number of moles of NaCl=Given mass/molar mass
Given mass of NaCl=14.3 g
molar mass of NaCl=58.44g
Number of moles of NaCl= 14.3/58.44
=0.244
Mass of solvent (Water)=42.2 g
Molarity=0.244*1000/(42.2)
= 5.80m

Barb tested the streak and luster.
Explanation:

Handle of frying pan would be a
good use for a nonmetal. A nonmetal is neither a good thermal insulator nor a
good electrical conductor. Because it is neither, it can be use as a semiconductor.
It does not absorb heat that much that is why it is best in insulating.
