Question

In an experiment the following reactions takes place:

$X + Y \to Z 2 g 4 g u g$

$Z + A \to B u g 7 g c g$

What is the value of u and c respectively?

Solution

According to the law of conservation of mass, the total mass of reactants is equal to the total mass of products.
For,
$X + Y \to Z 2 g 4 g u g$

Mass of Z = Mass of X + Mass of Y
$\Rightarrow$ u = (2+4) g = 6 g

Similarly for,
$Z + A \to B u g 7 g c g$

Mass of B = Mass of A + Mass of Z
$\Rightarrow$ c = (u + 7) g = (6 + 7) g = 13 g.
Hence, the mass of Z= 6 g and mass of B = 13 g.
