Answer:

$m_{Sn}=630.57gSn$

Explanation:

Hello!

In this case, according to the chemical reaction:

$SnO_2+2H_2\rightarrow Sn+2H_2O$

We can evidence the 2:1 mole ratio between hydrogen and tin, thus, we perform the following stoichiometric setup to obtain the mass of produced tin:

$m_{Sn}=21.46gH_2*\frac{1molH_2}{2.02gH_2}*\frac{1molSn}{2molH_2} *\frac{118.71gSn}{1molSn} \\\\m_{Sn}=630.57gSn$

Best regards!
