Hi I just needed some help with the question below. Calculate how much acid and base you need to make 100ml of each buffer at an overall molarity of 0.1M.

Acid- NaH2PO4 molecular weight - 156.01.

PH 5.8 - 95.1 mM
PH 6.6 - 59.87 mM
PH 7.4 - 24.6 mM

Base Na2HPO4- molecular weight - 177.99

PH 5.8- 4.9 mM
PH 6.6 - 40.28 mM
PH 7.4 - 75.4 mM

Bis the answerhope it !

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

Answer the same molecular formula;

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. this makes plastics which are important also to people but sometimes it lead to harmful environmental effects such as global warming if these plastics are burned.
