This can be solved by ratio and proportion. In 100g of water, you can dissolve 8.00 g of the substance. In 250g of water, you can dissolve x g of the substance.
In equation,
100/8 = 250/x
x = (250*8)/100
x = 20.0 g

Nitrites then to be soluble (keep your powder dry). Most sulfates are soluble (Pb and Ba are not so soluble), Carbon disulfide, a liquid, absorbs through the skin, very dangerous!. might react, dissolve? check the CRC (Chemical rubber handbook) unlikely, Hg, an element, slow to oxidize, unlikely, Benzene. Unlikely.
