moles = mass/Mr moles = 100/(23+16+1) moles of NaOH = 2.5mol
One gram of NaOH is equal is to 0,00225 moles.
Molecular mass of NaOH= 40.0 grams9.40 grams / (40.0 grams) = .235 moles NaOH
0,15 moles NaOH contain 6 g.
1.4 moles - the HCl is the limiting ingredient
Balanced Equation. NaOH + HNO3 >> NaNO3 + H2O Now, Molarity = moles of solute/liters of solution 0.800M HNO3 + mol/2.50L mol of HNO3 = 2 2mol HNO3 (1mol NaOH/1molHNO3 )(39.998g NaOH/1mol NaOH ) = 79.996 grams
Na + 2H2O -----> H2 + NaOH If you have 2.5 moles water you need 1.25 mol elemental sodium
0.75 moles in 30.0g of NaOH.
Molarity = moles of solute/Liters of solution 3.42 M NaOH = 1.3 moles NaOH/Liters NaOH Liters NaOH = 1.3 moles NaOH/3.42 M NaOH = 0.38 Liters
8 grams NaOH (1 mole NaOH/39.998 grams) = 0.2 moles NaOH
208g NaOH
The number of moles is 0,0038.
Molarity = moles of solute/liters of solution ( 15ml = 0.015 liters ) 2.9 M NaOH = moles NaOH/0.015 liters = 0.0435 moles of NaOH
Molecular mass of NaOH= 40.0 grams9.40 grams / (40.0 grams) = .235 moles NaOH
You need 2,4 g NaOH (0,06 moles).
The same number of moles for each.
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
3.42 moles NaOH (39.998 grams/1 mole NaOH) = 137 grams NaOH
how many moles are in 95.0 gram of octane?
