WebConvert that number of moles into grams if you are asked for a mass. The calculation looks like this: 1 mol O 2 weighs 2 x 16 = 32 g. 1.60 g is 1.60/32 = 0.0500 mol. The equation says that 1 mole of oxygen is produced from 2 moles of potassium nitrate. So you must have started with 2 x 0.0500 mol KNO 3 = 0.100 mol. WebH2SO4+ 2NaOH → Na2SO4 + 2H2 moles H 2SO4 = ࠵?࠵?࠵?࠵?࠵? ࠵?࠵?= 250 mol moles NaOH = 2 x 250 = 500 mol mass NaOH = 40 x 500 = 20000 g O H 2 SO 4 + 2 NaOH → Na 2 SO 4 + 2H 2 O …
