Question

Qual a massa de CO₂ que reage com 10 mols de CₐO? Dadas as massas molares: CₐO = 56g/mol CO₂ = 44g/mol CₐCO₃ = 100g/mol

Answer 1

56g    -----    1mol

 x      -----    10mol

x = 56 * 10

x = 560g

    CO₂               CaO

44g   -----   56g/mol

 m    ------  560g/mol

m * 56 = 560 * 44

m = $\frac{560*44}{56} = 10* 44$

m = 440g
