How many grams of solid koh must be added
Web1 Gram (g) is equal to 0.001 kilogram (kg). To convert grams to kg, multiply the gram value by 0.001 or divide by 1000. For example, to convert 100 grams to kg, multiply 100 by 0.001, that makes 0.1 kg in 100 grams. grams to kilograms formula. kilogram = gram * 0.001. kilogram = gram / 1000. How to convert kilograms to grams? WebTake 10 ml of 1M NaCl, how much NaCl is there in that? Answer: amount concentration volume = amount concentration volume= × Amount in 10ml = 10ml x 1mol.L-1 x 0.001 L.mL-1 = 0.01mol So imagine that you are taking 10ml which has 0.01mol salt in it, and you put it into a total volume of 100ml.
