The approximate molar mass of Al(OH)3 = 27 + 48 + 3 = 78 g/mol
150 g x 1 mol/78 g = 1.92 moles
150 grams of Al(OH)3 correspond to 1,923 moles.
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
The reaction equation is 2 NaHCO3 + H2SO4 = 2 CO2 + 2H2O + Na2SO4. This means that for every mole of sulfuric acid, two moles of NaHCO3 are needed. 150 grams of H2SO4 is 1.53 moles, so 3.06 moles of NaHCO3 are required.
150/132 equals 1.136moles
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
75 g sodium chloride in 150 mL water is a supersaturated solution.
Divide by molar mass of NaCl (not NaCI ! ) which is 58.44 g/mol NaCl.
Several part problem. Get molarity of NaHCO3. (150 ml)( M NaHCO3) = (150 ml)(0.44 M HCl) = 0.44 M NaHCO3 --------------------------- get moles NaHCO3 ( 150 ml = 0.150 Liters ) 0.44 M NaHCO3 = moles NaHCO3/0.150 Liters = 0.066 moles NaHCO3 ---------------------------------------get grams 0.066 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 5.54 grams NaHCO3 needed ---------------------------------------------answer
150 grams is approximately 5.3 ounces.
No you need more copper
150 Milligrams = 0.15 Grams
150 grams = 5.3 ounces
150 grams of water is approximately 10 tablespoons
150 grams of polenta is about 7/8 of a cup.
150 pounds approximately equals 68,038.855 grams
(1000 grams) / (150 grams) = 6.66666667150 grams * 6.66666667 = 1 kilograms1 kilogram = 1000 grams
150 M NaOH = 150 mole / liter 20.0 mL = 0.0200 L 150 * 0.0200 = 3 moles
45 grams H20 x (1 mole H20/18 grams H2O) x (6.02E23 molecules H20/1 mole H2O) the grams H2O and moles H2O cancel out. When you punch it into your calculator, the answer comes out to: =1.505E24 molecules H2O
