Question 3

Chemistry
1 answer:

Answer: 0.118M

Explanation:

The formula for molarity is: M=\frac{mol solute}{L solution}

First, we need to find the number of moles of NaCl.

2.70gNaCl*\frac{1molNaCl}{58.44gNaCl} =0.05molNaCl

Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.

\frac{425mL}{1000} =0.425L

Now we have our needed data! All we need to do now is plug in our data to the molarity formula.

M=\frac{0.05mol}{0.425L} =0.118M

I hope this helps! Pls mark brainliest!! :)

KATRIN_1 [288]
C5H12 (l) + 8O2 (g) ----> 5CO2 (g) + 6H2O (l)
Delta H = -3505.8 kJ/mol

C (s) + O2 (g) -----> CO2 (g)
Delta H = -393.5 kJ/mol

H2 (g) + (1/2)O2 (g) ------> H2O (l)
Delta H = -286 kJ/mol

Possible answers:
a. +35 kJ/mol
b. + 1,073 kJ/mol
c. -4,185 kJ/mol
d. -2,826 kJ/mol
