Power source (battery/energy) a copper/metal wire, and then a receiver
First, we determine the energy required to melt one gram of ice. This is given by:
Energy = mass * latent heat of fusion
Energy = 1 g * 334 J/g
Energy = 334 J
Next, we use Planck's equation which is:
Energy = number of photons * Planck's constant * speed of light / wavelength
334 = n * 6.64 x 10⁻³⁴ * 3 x 10⁸ / 5.49 x 10⁻⁶
n = 9.20 x 10²¹
9.20 x 10²¹ photons need to be absorbed by the ice.
Based on the information provided and the assumption that the mole ratio of the acid to the base is 1:1, the molarity of the acid would be 0.0425 M
<h3>Acid/base Titration</h3>
Using the equation:
CaVa = CbVb
This is based on the assumption that the stoichiometric mole ratio of the acid to the base is 1:1.
Ca = CbVb/Va
0.1 x 25.5/60 = 0.0425 M

True, to convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
Explanation:
To solve this question, we need to use the following formula:
M = n/V
So:
M = ??
n = 2.634 mol
V = 25.2 L
M = 2.634/25.2
M = 0.105 mol/L
Answer: a. 0.105
