The answer would be choice B because the energy decreased by 20 J
Molarity of solution is mathematically expressed as,
M =
We know that volume = mass/density
Given: mass of solution = 100 g, Density = 1.34 g/ml
∴ volume = 100/1.34 = 88.49 ml = 0.08849 l
Also, we know that molecular weight of sucrose = 342.3 g/mol
∴M =
= 6.979 M
Thus, molarity of solution is 6.979 M
Acceleration can be described as changes in speed, changes in direction, or changes in both. Acceleration is a vector.
Answer:
Energy is released when bonds are broken, and energy is absorbed when bonds are formed.
