How many moles would be contained in 5.80 liters of a 1.30 M solution? *

There are 7,54 moles in 5,80 liters of the solution 1,30M.

Explanation:

We know that molarity is a concentration measure that expresses the moles of solute per liter of solution: in this case, being 1.30 molar, there are 1.30 moles of solute in 1 liter of solution. We solve with the following simple rule of three:

1 L solution1, 30 moles of solute

5,8 L solutionx= (5,8 L solution x 1, 30 moles of solute)/1 L solution

x=7,54 moles of solute

i'm pretty sure its b i might be wrong though!

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
