We have 495 ml, but we need to convert this to 1000, so we divide by 495 and multiply by 1000. We also do this to 21.1g. 21.1/495*100 is 42.626g. KI's molecular weight is 166g/mol. 42.626/166 is 0.2568 molar.

To make water using NaOH, you can react it with an acid, such as HCl. The reaction isNaOH + HCl ---> NaCl + H2O. 2.75x10^4 moles of NaOH will produce 2.75x10^4 moles of water because the ratio of NaOH to H2O is 1 to 1 (see equation). Thus, the mass of water formed will be2.75x10^4 moles H2O x 18 g/mole = 4.95x10^5 grams of water (495 kg)
495g = 17.46oz
495g = 17.5oz
There are 1000 grams in one kilogram. Therefore, 495 kilograms is equal to 495 x 1000 = 495000 grams.
There are 16 ounces in one pound. Therefore, 7920 ounces is equal to 7920 / 16 = 495 pounds.
495 g = 1.091 pounds.
There are 10 millimetres in one centimetre. Therefore, 495 millimetres is equal to 495/10 = 49.5 centimetres.
There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 495 kilometres is equal to 495/1.609344 = 307.58 miles.

165/495 is one of infinitely many possible answers.
As of January 13, 2012: 495 GBP = 758.1915
33 feet multiplied by 15 feet is equal to 495 square feet.
90 * 5.50 = 495
