I need an explanation of this sentence:
Firstly, SnCl4.5H2O with fixed at 0, 1, 3, and 5 mol% of TiO2 and Titanium (IV) isoproxide (TTIP) with fixed at 10 ml were mixed into 150 ml of ethanol (C2H5OH) and.
what is the meaning of (fixed at), and what is the meaning of (0, 1, 3, and 5 mol%)?
how do I find the volume of SnCl4.5H2O, TiO2, and Titanium (IV) isoproxide (TTIP)?
