Answer:
# of protons: 17
Mass #: 36
#of electrons: 17
Element: Chlorine (Cl)
Explanation:
# of protons: based on atomic#
Mass #: protons+neutrons
#of electrons: based on atomic# if it's neutral charge
Element: use the Periodic Table to find element 17 (each element has their corresponding atomic#)
I'm not 100% sure but I think it's strontium

Answer:
A substance that is present at the end of a chemical reaction.
Percentage mass of water in SrCl₂<span>·6H</span>₂O
= (6 x 18) / (88 + 35.5 x 2 + 6 x 18)
= 40.4%
Mass of water in sample originally₂:
118.63 x 40.4%
= 47.9 grams
Percentage remaining = (47.9 - 34.81) / 47.9 x 100
= 27.3%
