The molar mass of tin(II) chloride is: 84.9 g
Calculate the molar mass of tin(II) chloride?
The number of moles n1 is thus:
n1= m1/M1 = 2.25 mol
According to the balanced reaction, the ratio by number of moles n of tin(II) chloride produced to the number of moles n1 of HF used is 1:2
As such, the number of moles of tin(II) chloride produced is :
n = 1/2 [tex]n_{1}[/tex] = 0.45 mol
The molar mass of tin(II) chloride is:
M= A[tex]_{r}[/tex](Sn)+2A[tex]_{r}[/tex](Cl) = 188.7 g/mol
The mass m produced is thus:
m = nM
= 0.45 mol × 188.7 g/mol
≈ 84.9 g
Therefore, the molar mass of tin(II) chloride is: 84.9 g.
