M = mols of solute / L of solution
Convert .50 g Na to mols Na by dividing by 22.99 and then dividing that by 1.5, which gives you a 0.014 M solution.
C. Speed is how fast, velocity has direction and acceleration is a change in velocity.
<span>The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases. you can look it up in Google</span>
