How many grams of nacl will be needed to form 600 ml of a saturated solution at 100°c? 15 g 24 g 40 g 240 g

The saturation of NaCl at 100 ° C. is 39.8 g / 100 ml.

To calculate the amount of NaCl, Cross-multiplication should be used.

100ml ==> 39.8 grams

600ml ==> 39.8 * 600/100 = 238.8 grams of NaCl in the solution

So the answer should be the one that comes closest to this result is 240 grams.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
