A company needs 1.50 L of a 0.9% sodium chloride solution. They only have a 2.5% solution.
What is the volume of stock needed to make 1.50 L of 0.9% sodium chloride from a 2.5% stock
solution?
What is the total amount of sodium chloride in grams the final solution
If you have a 1 molar solutions of both potassium chloride and calcium chloride which will have
the greatest concentration of chloride ions. Justify your answer.

i think the answer would be reserve.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

magnets not strong enough
