What is the percent of Zn?

Q: A 3.00 g sample of a mixture contains copper and zinc. Zinc reacts with HCl according to the equation show below, but copper does not react with HCl. What is the percentage of Zn in the sample if 0.927 L of hydrogen gas is released at 0.974 atm and 293 K. (Atomic mass: Zn = 65.39, H = 1.008, Cl = 35.45, O = 16.00; R = 0.0821 L atm mol-1 K-1).Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)85.3%79.2%77.1%81.8%None of the above are correct.

What is the isotopic abundance of Zinc?

Q: My text book says that there are two isotopes, Zn-64 (63.9292 amu) and Zn-72 (71.9278 amu), but it gives no percents. So it would go like this:atomic mass Zn=(63.9292 * % / 100) + (71.9278 * % / 100)So, I’m kinda lost without the %. Please help me out with the percents, or give me a way I can find them

A: Atomic mass Zn = 65.39 amulet x = % Zn-64let y = % Zn -72x + y = 100x = 100-y65.39 = 63.9292 ( 100 – y) + 71.9278 y / 100solve for yNote : Zn does not have an isotope Zn- 72
