Calculate the volume in liters required to prepare a 5.00 m solution of nacl using 15.4 g of nacl

52.7 ml First, determine how many moles of NaCl you have Atomic weight sodium = 22.989769 Atomic weight chlorine = 35.453 Molar mass NaCl = 22.989769 + 35.453 = 58.442769 g/mol Moles NaCl = 15.4 g / 58.442769 g/mol = 0.263505653 mol Now molarity is defined as moles/liter, so let's set up an equation for the number of liters we can make. molarity = moles/liter Substitute the known values 5.00 = 0.263505653/liter And solve for liters 5.00 = 0.263505653/liter 5.00* liter = 0.263505653 liter = 0.263505653/5.00 liter = 0.052701131 So you can make 0.0527 liters of the solution. Or 52.7 ml

D.na is the answer hope this

Answer : option c) heat is released during the process.explanation :

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.
