Answer:
1.352 M
Explanation:
Molarity is equal to the moles of the substance divided by the volume in Liters. First convert mL to L. 500.00 mL is 0.50000 L. Divide 0.6762 by 0.5 and remember to keep a maximum of 4 significant figures. :)
The body of theory which explains physical properties of matter in terms of the motions of its constituent particles.
<span>The answer is\ compound, B. A compound is a particle made of molecules from various components. All mixes are particles, however not all atoms are mixes. Hydrogen gas (H2) is an atom, however not a compound since it is made of just a single component.</span>

Answer:
0.56 M
Explanation:
Step 1: Given data
- Rate constant (k): 0.035 s⁻¹
- Initial concentration of the reactant ([A]₀): 1.5 M
Step 2: Calculate the amount of reactant ([A]) after 28 seconds
For a first-order kinetics, we will use the following expression.
ln [A] = ln [A]₀ - k × t
ln [A] = ln 1.5 - 0.035 s⁻¹ × 28 s
[A] = 0.56 M
