Answer:
A 1 M solution corresponds to 1 mole of the solute (here, sodium chloride, NaCl) in 1 L of solvent (here probably water). Since the question calls for only making 250 mL, or 1/4 of a L, only 1/4 or 0.25 mol will be required. The molecular weight of NaCl is 58.44 g/mol so you will need:
0.25 mol * 58.44 g/mol = 14.61 g

Answer:
–169
Step-by-step explanation:
(f/g)(x) = ( 3 – 2x ) / (1 / x+5)
(f/g)(8) = (3 - 16)/(1/13)
(f/g)(8) = = -13 * 13
(f/g)(8) = - 169
