Epsom salt is MgSO4.
We assume x water of hydration in the crystalline form.
Molecular mass of MgSO4 = 24+32+4*16=120
Molecular mass of MgSO4.xH2O = 120+18x
By proportion,
2.000/0.977 = (120+18x)/120
Cross multiply
0.977(120+18x) = 120*2.000
from which we solve for x
17.586x+117.24 = 240
x=122.78/17.586
=6.980
Answer: there are 7 water of hydration in Epsom salt, according to the experiment.
Note: more accurate (proper) results may be obtained by using exact values (3-4 significant figures) in the molecular masses. However, since water of hydration is the nearest integer, using approximate values (to at least two significant figures) suffice.
Answer:
<u><em>During the colonial period, the arrival of sugar culture deeply impacted the society and economy in the Caribbean. It not only dramatically increased the ratio of slaves to free men, but it increased the average size of slave plantations</em></u>
<u><em>The negative impact of the slave trade on the development of the Caribbean islands. The slave trade had long lasting negative effects on the islands of the Caribbean. The native peoples, the Arawaks, were wiped out by European diseases and became replaced with West Africans</em></u>
<u><em>The sugar revolutions were both cause and consequence of the demographic revolution. Sugar production required a greater labor supply than was available through the importation of European servants and irregularly supplied African slaves</em></u>
