YUAssess question 3 Notyot answered
A student obtains the following data for a sample of $\mathrm{SrCl}_{2}, \mathrm{nH}_{2} \mathrm{O}$ 27.29 g
Mass of crucible: Mass of crucible and hydrate: 28.56 g
Mass of crucible and anhydrous residue after heating: 28.05 g
The correct formula of the hydrate is: $\mathrm{SrCl}_{2} 3 \mathrm{H}_{2} \mathrm{O}$ $\mathrm{SrCl}_{2} .4 \mathrm{H}_{2} \mathrm{O}$ $\mathrm{SrCl}_{2} \cdot 6 \mathrm{H}_{2} \mathrm{O}$ $\mathrm{SrCl}_{2} .7 \mathrm{H}_{2} \mathrm{O}$
