Answer:
The answer is
<h2>464 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of solution = 80 mL
density = 5.80 g/mL
The mass is
mass = 80 × 5.8
We have the final answer as
<h3>464 g</h3>

Rio Puerco valley. The Rio Puerco volcanic necks, including the regionally visible Cabezon Peak, are all part of the Mount Taylor volcanic field.
The correct answer among the choices given is option B. Radioisotopes are isotopes that emit radiation because they have unstable nuclei. These are radioactive isotopes of an element. They are defined as atoms that contain an unstable combination of neutrons and protons.
Answer:
c. although both are living organisms, parasite depend on the cells of living things to reproduce
Ba(OH)₂ is a strong base, therefore completely ionises in the solution as follows
Ba(OH)₂ --> Ba²⁺ + 2OH⁻
1 mol of Ba(OH)₂ gives out 2 mol of OH⁻
therefore number of OH⁻ moles are twice the amount of Ba(OH)₂ moles in the solution
hence,
[OH⁻] = 2[Ba(OH)₂]
therefore hydroxide ion concentration = 2 x 1.37 x 10⁻⁵ M
[OH⁻] = 2.74 x 10⁻⁵ M
coefficient = 2.74
exponent = -5
