Question

Part A Based on the tollowing data, complete the table below as if you were making the calculations described in the lab Cuso 26.30 g 30.25 Formula of Anhydrous Sah (suppied by instructor) Mass of Crucible Mass of Crucible + Hydrate What is the mass ofHydrate in grams? (DO NOT put units: grams will be assumed) 35 9 Previcus Amwers Correct Part B You dry the hydrate as instrucred in the lab procedure, noting down it's mass until it appears to no longer decrease (na more water bound in the sample) 29.88 28.82 Mass of Salt+Crucble (atter 1st heating) Mass of San Crucible (ater 2rnd heating) What is the Mass of Salt after second hesting tie dry Cus04 IDO NOT put units: grams is assumed) 252 Correct Part C so whan is the Mass of Water Iiberared during drying? DO NOT put units:grams is assumed)

Explanation / Answer

Part D:

Moles of anhydrous CuSO4 = mass of anhydrous CuSO4/ Molar mass of CuSO4

Molar mass of CuSO4 is 159.609 g / mole

Moles of anhydrous CuSO4 = 2.52 g / 159.609 g / mole = 0.016 mole

Part E :

Moles of water = masswater / Molar mass of water

Molar mass of CuSO4 is 18.015 g / mole

Moles of anhydrous CuSO4 = 1.43 g / 18.015 g / mole = 0.079 mole
