5. How many moles are in 58.6 L of Nitrogen gas (N.) at STP?
pantera1 [17]

Answer:

2.6166 moles

Explanation:

stp means: T=273k   p=101.3kpa

R= 8.31(constant)       v=58.6  

using the ideal gas law; pv=nRt

                                        101.3 x 58.6 = n x 8.31 x 273

                                         n= (101.3 x 58.6)\(8.31 x 273)

                                         n= 2.6166moles

Calculate the molarity of kcl in the solution if the total volume of the solution is 239 ml.
Akimi4 [234]
When concentration is expressed in molarity, this is equivalent to the number of moles of the solute per liter of solution. We are given with the amount of volume which is 239 mL or 0.239 L. However, there is no known information of the amount of solute. So, I can't give an exact answer. For sample purposes, let's just assume that there is 1 mole of KCl in the solution. The molarity would be:

Molarity = 1 moles/0.239 L = 4.184 M

8. How much enthalpy/heat is transferred when 0.5113
Gennadij [26K]
First convert to moles:
0.5113 g / 17 g/mol = 0.0301 mol

Now create a ratio based on the reaction provided to solve for the unknown:

4 NH3 / -905.4 kJ = 0.0301 mol NH3 / x kJ
x = -6.808 kJ
