Answer:
Does the article contain facts or only opinions? - B)
A
Industry uses only about 18% while the others use around 70-90% of water.
Is this english or whattttt
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

Where
Density of Quartz is Generally given as 2.7g/ml
Therefore

Therefore
Percentage of spt=0.02*100
Percentage of spt=2\%
