A 1.0 M solution of NaCl has a final concentration of 0.20 M and a final volume of 200 mL, what was the initial volume of the NaCl solution in mL?

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it
