We have that the weight in grams gained
[tex]W=(\frac{1240}{\rho(ml/g)})*g[/tex]
From the Question we are told that
Volume [tex]v= 1240 ml[/tex]
Considering
Density of Beer =\rho
Generally the equation for the density is mathematically given as
[tex]\rho=\frac{1240}{m(hg)}[/tex]
[tex]m(g)=\frac{1240}{\rho(ml/g)}[/tex]
Therefore
Weight
[tex]W=m*g[/tex]
[tex]W=(\frac{1240}{\rho(ml/g)})*g[/tex]
