Recall that;
Speed = Distance/time
Distance = Speed * time
Speed = 200 km/h
Time = 4 hours
Distance = 200 km/h * 4 hours = 800 kilometres
Displacement has to do with distance covered in a specified direction, in this case, the direction is towards Zambales.
Hence, the displacement is 800 kilometres towards Zambales.
Answer: 4.22 grams of solute is there in 278 ml of 0.038 M 
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
Now put all the given values in the formula of molality, we get

mass of
= 
Thus 4.22 grams of solute is there in 278 ml of 0.038 M
