What mass of potassium iodide would dissolve in 175cm`³ of water at 30 °C if its solubility is 180g/100cm³ of water at 30°C? I'll give brainliest and 50 points for explanation

please answer

Your answer is, 195 g of dissolved potassium iodide

Now, this solubility graph expresses the solubility of potassium iodide per 100 cm3 of water, but you can use it as a measure of the salt's solubility per 100 g of water. Notice that at 40∘C, a saturated potassium iodide solution will contain about 195 g of dissolved potassium iodide.

i think its 100.

hope this !
