It is 25 moles of Sodium Hydroxide (;
the molar mass of sodium hydroxide is 40g/mol mike
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
The molar mass of NaOH is 39.9 g/mol, so if you multiply is by 2.5, you get the answer. 99.75 g/mol
0,15 moles NaOH contain 6 g.
Hydrochloric Acid is a Compound. Molecular formula: HCl Molecular Mass: 36.46 g/mol
the molar mass of sodium hydroxide is 40g/mol mike
Molar mass of NaOH is 39.998 grams. So, 2.75 mol NaOH (39.998g NaOH/1 mol NaOH) = 109.9945 grams NaOH ( you do the sigi figi )
0.2 mol
39.997 g mol-1
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
The molecular weight of sodium hydroxide is 40. Therefore 0.150 moles would be 40 x 0.15 = 6g.
The molar mass of NaOH is 39.9 g/mol, so if you multiply is by 2.5, you get the answer. 99.75 g/mol
Calculate the mass (in grams) of sodium sulfide that is needed to make 360ml of a 0.50 mol/L solution
0,15 moles NaOH contain 6 g.
Hydrochloric Acid is a Compound. Molecular formula: HCl Molecular Mass: 36.46 g/mol
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
The molar mass of NaNO3 is 84.9947 g/mol. Multiplying by 0.254 mol gives 21.5886538 g, or correctly sigFig'd, 21.6 g
