Answer 1

`m_(Sn)=630.57gSn`

Step-by-step 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*(1molH_2)/(2.02gH_2)*(1molSn)/(2molH_2) *(118.71gSn)/(1molSn) \\\\m_(Sn)=630.57gSn`

Best regards!
