ANSWER ASAP‼️ 1: What temperature is required to dissolve 30g of KClO3 in 100g H2O?

2:How many grams of KCI are required to saturate 100 grams of water at 60°C?

3:If 28 grams of KClO3 is dissolved at 60°C, how many additional grams KClO3 would be needed to make the solution saturated at 80°C?

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the answer would be a
