First, we determine the mass of stearic acid in the solution by multiplying the given concentration by the volume.
mass of stearic acid = (5.4 x 10^-4 g/L) (0.25 mL) (1000 mL/1L)
= 0.135 g
Then, we divide this amount by the molar mass in order to obtain the number of moles of stearic acid. The molar mass of stearic acid is 284.4772 g/mol.
moles stearic acid = 0.135 g / (284.4772 g/mol)
= <em>4.75 x 10^-4 mol</em>
I know the decimal is .56 i hope someone knows the fraction

Answer:
Given, Mass of an object, m = 2kg
velocity, v = 2m/s
We have,
KE = 1/2 m v²
= 1/2 × 2 (2)²
= 1/2 × 8
= 4J
Hence, 4J is the required Kinetic energy.
