What mass in grams of tin would be required to completely react with
1.50 L of 0.750 M HBr in the following chemical reaction?
Sn(s) + 4 HBr(aq) - SnBr (aq) + 2 H₂ (g)



Answer :

Mass in grams of tin would be required to completely react with 1.50 L of 0.750 M HBr in the following chemical reaction is 36.19g

Mass in gram is the amount of that compound that has the same mass in grams as the formula mass in atomic mass unit

Here given reaction is

Sn + 4HBr → SnBr  + 2H₂

Mole of HBr  = 1.50L × 0.750 M

= 1.125 mol

From balanced equation 4 mole of HBr react completely with one mole of tin to form the said product

Therefore, 1.125mole of HBr react completely with 1/4×1.125= 0.2812 mole of tin to form the said product

Molar mass of ton is 118.71g/mol

Mass of tin required = 0.2812×118.71

36.19g
