On heating a 1.687-g sample of the hydrate, 0.824 g of MgSO4 remains. How many molecules of water occur per formula unit of MgSO4? Answers to Mole Conversion Review Worksheet One Step and Molar Mass 132.1 g (NH4)2SO4 115.7 g Li3PO4 108.0 g N2O5 3.89 mol Fe2(CO3)3 1.1 x 103 g...
The moles of acid may then be calculated: (45.00 mL NaOH)(0.1000 mol NaOH/1000 mL) (1 mol HA/1 mol NaOH) = 4.500 × 10–3mol HA The molecular mass is: 0.2720 g/4.500 × 10–3mol =60.44 g/mol You get 1 point for the correct number of moles of HA (or NaOH) and 1 point ...
(ref. 44), respectively, mass balance consideration requires that d13C of HCO3À derived from methanogenesis be þ 150% based on equations (3) and (4). Our calculation shows that MT microspar precipitation at 100 m water depth would be B1% heavier than host rock (black solid line in...
At laparoscopy a mass attached to right ovary, suggestive of a right ovarian ectopic pregnancy, was excised. Histological examination confirmed an ovarian ectopic gestation, but noted enlarged chorionic villi and trophoblastic atypia, which raised the suspicion of molar pregnancy. Subsequent p57 ...
Calcium hydroxide, Ca(OH)_2, is almost insoluble in water; only 0.50 g can be dissolved in 1 L of water at 25 degrees C. If the dissolved substance is 100% dissociated, what is the pH of a saturated solution of calcium hydroxide? (Molar mass of Ca(OH)...
