The answer for this question is c
Number of mole : mass/ molar mass
87g/ (2 x 16) = 2.719 mol
volume = number of mole x molar volume
volume = 2.719 x 22.4
volume = 60.906 L
Answer:
1.08 g/mL
Explanation:
Density=Mass/Volume therefore you would do the mass which is 7.481 g divided by the volume which is 6.9 mL and get 1.08 g/mL since you combine the two labels!
1. I think you chose the right answer, the equation has the states of the reactants and products.
2. I think you chose the right answer.
3. I think you also chose the right answer. Assuming that the Hrxn is written as kJ per mol CH4
4. Heat of solution is the enthalpy change associated with dissolving a solute in a solvent. I think the first choice is the right one.
5. I think you chose the right answer.
