Answer:
mass of solute (m1) = 5.0 g NaCl
mass of solvent (m2 ) = 80.0 g H2O
T% = ( m1 / m1 + m2 ) * 100
T% = ( 5.0 / 5.0 + 80.0 ) * 100
T% = ( 5.0 / 85.0 ) * 100
T% = 0.0588 * 100
T = 5.88%
Explanation:
Option 4, 'a quote from a customer describing how much their electric bill was lowered,' best supports evidence that solar panels save money. You are using a first hand source to prove to the audience that solar panels save money.
