Question

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)

Answer 1

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

$3.10x+(2.6-\rho)*1=2.7$

Where

Density of Quartz is Generally given as 2.7g/ml

Therefore

$3.10-\rho=2.7\\\\2.1=0.05\\\\\rho=0.02$

Therefore

Percentage of spt=0.02*100

Percentage of spt=2\%
