Answer:
1250kg
Explanation:
Given parameters:
Acceleration = 1.2m/s²
Force = 1500N
Unknown:
Mass on the vehicle = ?
Solution:
According to newton's second law of motion:
Force = mass x acceleration
Since mass is the unknown, insert the parameters and solve;
1500 = mass x 1.2
mass = = 1250kg
The molar heat of fusion of X has been 775.6 cal/mol. Thus, option C is correct.
The molar heat of fusion has been defined as the energy absorbed or released by a mole of substance in converting between solid and liquid state.
<h3>Computation for the molar heat of fusion</h3>The given mass of substance X has been, 326 g.
The molar mass of substance X has been 58.45 g/mol.
The moles of sample have been given as:
Thus, the amount of heat absorbed by 5.58 mol of sample has been 4325.8 cal.
The amount of heat absorbed by a mole of sample has been:
The amount of heat absorbed by a mole of sample in meting has been the molar heat of fusion.
Thus, the molar heat of fusion of X has been 775.6 cal/mol. Thus, option C is correct.
