According to the following reaction, how many grams of chlorine gas are required for the complete reaction of 25.5 grams of iron? iron (s) + chlorine (g) iron(III) chloride (s)
grams chlorine gas

48.4 g of will be produced from 25.5 g of iron

Explanation:

To calculate the moles :

The balanced chemical reaction is:

According to stoichiometry :

2 moles of require  = 3 moles of

Thus 0.455 moles of will require=  of

Mass of

Thus 48.4 g of will be produced from 25.5 g of iron

answer is: empirical formula is tl₂o. if we use 100 grams of compound, tha:

m(tl) = 96.2%  · 100 g ÷ 100%.

m(tl) = 96.2 g.

n(tl) = m(tl)  ÷ m(tl). n(tl) = 96.2 g  ÷ 204.4 g/mol.

n(tl) = 0.47 mol. m(o) = 3.77 g. n(o) = m(o)  ÷ m(o). n(o) = 3.77 g  ÷ 16 g/mol. n(ag) = 0.235 mol. n(tl) . n(o) = 0.47 mol : 0.235 mol /0.235. n(tl) . n(o) = 2 : 1.

m(tl₂o) = 204.4 g/mol  · 2 + 16 g/mol = 424.8 g/mol.

m(compound) = 456. 8 g/mol - 424.8 g/mol = 32 g/mol ( 2 oxygens); tl₂o₃.
