We have that the percentage of SPT (3.10 g/mL) present in a solution with a density of 2.60 g/mL is
Percentage of spt=2\%
From the question we are told
What percent of SPT (3.10 g/mL) is present in a solution with a density of 2.60 g/mL, suitable to separate quartz and feldspar? The other component of this solution is water (1.00 g/mL)
Generally the equation for the Desired SPT is mathematically given as
[tex]3.10x+(2.6-\rho)*1=2.7[/tex]
Where
Density of Quartz is Generally given as 2.7g/ml
Therefore
[tex]3.10-\rho=2.7\\\\2.1=0.05\\\\\rho=0.02[/tex]
Therefore
Percentage of spt=0.02*100
Percentage of spt=2\%
