Milk of magnesia, a suspension of mg (oh) 2 in water, reacts with stomach acid (hcl) in a neutralization reaction. mg (oh) 2 (s) + 2 hcl (aq) - → 2 h2o (ℓ) + mgcl2 (aq) what mass of mgcl2 will be produced if 1.82 g of mg (oh) 2 reacts? answer in units of g.

Balanced equation for the above reaction is as follows;

Mg (OH) ₂ + 2HCl - - - > MgCl₂ + 2H₂O

stoichiometry of Mg (OH) ₂ to MgCl₂ is 1:1

mass of Mg (OH) ₂ reacted - 1.82 g

number of moles of Mg (OH) ₂ - 1.82 g / 58.3 g/mol = 0.0312 mol

number of Mg (OH) ₂ moles reacted - number of MgCl₂ moles formed

number of MgCl₂ moles formed - 0.0312 mol

mass of MgCl₂ formed - 0.0312 mol x 95.2 g/mol = 2.97 g

mass of MgCl₂ formed - 2.97 g
