When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.
Net overall dissociation:
Na2CO3 ---> 2Na(-) + CO3(2-)

<span> Dmitri Mendeleev and Lothar Meyer individually came up with their own periodic law "when the elements are arranged in order of increasing atomic mass,
certain sets of properties recur periodically.</span>
Answer:
A base.
Explanation:
Basic solutions give OH- ions.
The SI unit for distance is metres - m.
The SI unit for speed or velocity is metres per second - m/s.
The SI unit for acceleration is metres per second squared. - m/s^2.
