See solution.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to set up the formula for the calculation of the by-mass percentage of the metal:

Thus, we solve for the molar mass of the metal to obtain:

For the subsequent problems, we proceed as follows:
a.

b.

c.

Answer:
2.0 mL of 10.5 M H2O2, where H2O2 has a molar mass of 34 g/mol.
Explanation:
It is most concentrated because it contains 10.5 M of Hydrogen peroxide.
The Geiger Counter. Geiger counters are used to detect radioactive emissions, most commonly beta particles and gamma rays. The counter consists of a tube filled with an inert gas that becomes conductive of electricity when it is impacted by a high-energy particle.
Hope That Helps!!!
