The answer is marbles
250 gm of salt.
When salt is dissolved in water it does not increase the volume of the water. 51.3 grams of salt in 1000 grams of water is equal to .0513, or 5.13 percent salt.
The mass of salt is 1,42 grams.
290 grams
Weight and length are not comparable without other factors. I assume you meant milligrams though. There are 2900 milligrams in 2.9 grams of salt.
grams are weight, while teaspoons are volume. A teaspoon is 4.93 milliliters.
Weigh it in grams, then, as the density of table salt is about 2.17 g/cc, divide the weight by 2.17 and the answer will be the volume of salt in cc.
You might try dissolving the same weight of rock salt and table salt in the same amount of distilled water and seeing how the solutions match up for clarity.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
5 grams of salt in 10 grams of water is more concentrated (50%) compared to 18 grams of salt in 90 grams of water (20%).
