22. naturally occurring hydrogen consists of three isotopes, hydrogen-1 (1.07 u)
hydrogen-2 (2.02 u) and hydrogen-3 (3.01 u), where the isotopic masses are given
parentheses. use the periodic table and determine which isotope is present inue
larger percentage in the natural element.
a. hydrogen-1
b. hydrogen-2
c. hydrogen-3
d. each is present at equal percentages.

The answer to your question is: a. Hydrogen-1

Explanation:

Hydrogen-1 (1.07 u)

Hydrogen-2 (2.02 u)

Hydrogen-3 (3.01 u)

Periodic table says that H has an atomic mas of 1.008

Then, the reported atomic mass is closer to the mass of the smaller isotope, so Hydrogen-1 must be present in larger percentage.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
