WebThe solution was cooled and 2,4,6- trimethylbenzeneboronic acid (6.56 g, 40 mmol) dissolved in 40 mL of 1,2 dimethoxyethane was added. Finally, potassium t-butoxide (8.97g, 80 mmoL) was added as a solution in 40 mL of t-butanol. The reaction was heated for 0.5 h at 90 °C. The solution was cooled and filtered through celite.
How many total moles of ions are released when the following …
WebCorrect option is C) The molecular mass of Ba(OH) 2=315.4639 g/mol It is given that 5.6g in 100 g of water which is same as 56g in 1 kg of water. So, number of moles of Ba(OH) 2 in 1 kg of water = 315.463956 =0.1775 mol. The dissociation of Ba(OH) 2 is, Ba(OH) 28.H 2O→Ba 2++2OH −+8H 2O 1 mole of Ba(OH) 2 produces 2 moles of OH − ions WebHow many total moles of ions are released when the following sample dissolves completely in water? 4.98 g of Ba (OH)2 · 8H2O: mol Expert Answer 100% (3 ratings) Mass of Ba (OH)2 · 8H2O = 4.98 g Molar mass of Ba (OH)2 · 8H2O = 315.42 g/mol Mole … View the full answer Previous question Next question free literacy resources for parents

WebAug 19, 2024 · The question asks for how many grams of H 2 (g) were released so the moles of H 2 (g) must still be converted to grams using the molar mass of H 2 (g). Since there are two H in each H 2, its molar mass is twice that of a single H atom. molar mass = 2(1.00794g/ mol) = 2.01588g/ mol. 3.74 x 10-5 mol H 2 (g) (2.01588g H 2 (g)/ 1mol H 2 … free literati game online
