To find the mass of F in 34.6 g of SnF2, we need to determine the molar mass of SnF2 and then use the molar ratio between F and SnF2.
The molar mass of SnF2 can be calculated by adding the atomic masses of each element:
Molar mass of SnF2 = (atomic mass of Sn) + 2(atomic mass of F)
The atomic mass of Sn is 118.71 g/mol, and the atomic mass of F is 18.9984 g/mol.
Molar mass of SnF2 = 118.71 g/mol + 2(18.9984 g/mol)
Molar mass of SnF2 = 156.7068 g/mol
Now we can calculate the mass of F in 34.6 g of SnF2 using the molar ratio:
Mass of F = (34.6 g SnF2) x (2 mol F / 1 mol SnF2) x (18.9984 g F / 1 mol F)
Mass of F = 34.6 g x (2 x 18.9984 g / 156.7068 g)
Mass of F = 34.6 g x 0.2436652
Mass of F = 8.432 g
Rounding to three significant figures, the mass of F in 34.6 g of SnF2 is 8.43 g.
