Question

MnO2 formula mass= molar mass=

C5H12 formula mass= molar mass=

XeF6 formula mass= molar mass=

Answer 1

Mn = 54,93
O = 15,999
MnO2 = 54,93 + (2*15,999) = ??? g/mol

C = 12,011
H = 1,008
C5H12=(5*12,011)+(12*1,008) = ??? g/mol

Xe = 131,29
F = 18,998
XeF6 = 131,29 + (6* 18,998) = ??? g/mol

Answer 2

so 86.91 formula mass and 86.936845 molar mass

Answer 3

you wrote yourself
formula mass= molar mass
so it is for MnO2 = 86,928 g/mol

Answer 4

Thanks!

Answer 5

not a problem ;)
