Answer:
b is the answer my brudaa
Explanation:
Answer is: .408,5 J.m(C₆H₆-benzene) = 39 g.
n(C₆H₆) = m(C₆H₆) / M(C₆H₆) = 39g ÷ 78g/mol = 0,5 mol.ΔT = 10,0°C, difference at temperature.c(benzene) = 81,7 J/mol·°C, specific heat of benzene.Q = n(benzene) · ΔT · c(benzene), heat of reaction.Q = 0,5 mol · 10,0°C · 81,7 J/mol·°C.Q = 408,5 J.
Answer:
17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.
Explanation:

We have:
Molarity of the NaCl solution = 6.32 M
Volume of the NaCl solution = 2,719 mL =2,719 × 0.001 L= 2.719 L
1 mL = 0.001 L
Let the moles of NaCl be n.


17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.
