If you are making 500 ml of a stock solution of 10X PBS pH7.4. How much of each component you would need to add if the appropriate concentrations of 1x PBS are: a. NaCl: 137 mM
b. KCl: 2.7 mM
c. Na2HPO4: 10 mM
d. KH2PO4: 1.8 mM
e. MW NaCL= 58.44 g/mol
f. MW KCl = 74.55 g/mol
g. MW Na2HPO4= 141.96 g/mol
h. MW KH2PO4= 136.09 g/mol

I think answer should be h. Please give me brainlest I hope this helps let me know if it’s correct thanks bye okay thanks bye

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
