ABSTRACT By calculating the difference in the mass of the hydrate copper (II) sulfate and the anhydride we were able to determine the mass of water in the hydrate. This information was then used to determine the empirical formula of the hydrate‚ defined as a compound formed by the addition of water to another molecule. In the first trial‚ the mass of water in the hydrate was determined to be 0.41 g‚ while in the second trial the mass of water was 0.52 g. Moles of water associated with a single

These are the functions which we have to evaluate this week. fx=2x+3 gx=x2-3 hx=7-x3 We have been asked to compute(f-h)(4). So we can evaluate each separately and then subtract. f-h4=f4-h(4) f4=24+3 =8+3=11 f4=11 h4=7-43 =33=1 h4=1 This is our final answer. f-h4=11-1=10 Next we are to compare two pairs of the functions
