Answer:
For 6.50 mol NaOH - 1.44M.
For 6.50 g NaOH - C. 0.0361 M
Explanation:
For 6.50 mol NaOH.
Molarity = moles solute/L solution = 6.5 mol/4.5 L solution = 1.44 mol/L=1.44M
There is no such answer in given choices.
For 6.50 g NaOH
M(NaOH) = 23 + 16 + 1 = 40 g/mol
Molarity = 6.5g* 1 mol/40g *1/4.5L = 0.0361 mol/L = 0.0361 M
There is such answer. It is C.
The phrase 1 meter per second is a unit of velocity and is a unit of rate. 1 meter per second means for every second, for example, a man runs, he travels 1 meter distance. 1 meter per second is a derivative of the primary units of SI system, meter for distance and second for time.
