A 20 °C la solubilidad de Cloruro de potasio es 34 g/100 g de agua. En el laboratorio, un estudiante mezcla 175 g de KCl con 300. g de agua a una temperatura de 20 °C. ¿cuanto de cloruro potásico se puede disolver?, ¿La disolución es saturada o insaturada? *

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
