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
