Please help asap Above is a solubility curve for KNO3.

Solubility has nothing to do with the speed of dissolving; it's a measure of how much salt will dissolve at a given temperature.

The y-axis of the graph shows you how much KNO3 will dissolve in 100 g of water. In other words, it tells you the maximum amount of solute that will dissolve at different temperatures.

The x-axis tells you the minimum temperature needed to dissolve different amounts of KNO3 in 100 g of water.

Approximately how many grams of KNO3 will dissolve in 100 g water at 0 degrees Celsius?

Type in the number only; no units. Round your answer to the nearest whole number.

A100-watt light bulb radiates energy at a rate of 100 j/s. (the watt, a unit of power or energy over time, is defined as 1 j/s.) if all of the light emitted has a wavelength of 525 nm , how many photons are emitted per second?

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
