Can someone please help me with this question about solubility? At 20 degrees Celsius, a saturated solution of sodium nitrate contains 100 grams of solute in 100 mL of water. How many grams of sodium chlorate must be added to saturate the solution at 50 degrees Celsius?

@wilsondanielle can you please help me?

OpenStudy (wilsondanielle):

Is that all of the information they give?

OpenStudy (wilsondanielle):

Normally you'll get a plot or something similar - solubility is a function of temperature.

OpenStudy (anonymous):

i have a chart @wilsondanielle

OpenStudy (wilsondanielle):

Follow the chart and see what the solubility is at 50 degrees

OpenStudy (anonymous):

for which one @wilsondanielle

OpenStudy (wilsondanielle):

I can't really help you without the chart - but you should be able to look at the solubility of the solution at 50 degrees and solve the problem

OpenStudy (wilsondanielle):

something like this https://figures.boundless.com/30840/full/solubilityvstemperature.png is what you need - where solubility is plotted against temperature

OpenStudy (anonymous):

im gonna send the chart @wilsondanielle

OpenStudy (anonymous):

this is the chart

@wilsondanielle

OpenStudy (wilsondanielle):

ok so sodium chlorate is NaCl. Follow the line that says "NaCl" to where it intersects with the 50 degree line - that's how many grams will dissolve in whatever mL of solution (I can't make that out - I think it's 100?)

OpenStudy (wilsondanielle):

if it's not 100mL, just cross multiply to wind up with the appropriate volume.

OpenStudy (wilsondanielle):

Also : If I'm interpreting the question correctly you need to factor in the solute from the first part.

OpenStudy (anonymous):

its about 39 NaCl is the black line
