QUICK HELP PLEASE!!?? Need answer QUICK

What type of solution would you have if you dissolved 60g of Na2HAsO4 in 100g of 60oC water?

A. supersaturated

B. unsaturated

C. saturated

D. Cannot be determined

B

Explanation:

Look on the x-axis for the tick marked "60". This indicates 60 degrees Celsius, which we want. Now, look on the y-axis for the tick marked "60". This indicates 60 grams of . Trace along the graph to find where these two places meet at (60, 60).

Now, look for the solubility curve of ; it's the yellow-orange line. Find out what the y-coordinate of the point where x = 60 is on the line: it's around (60, 65).

So, since the point (60, 60) is below the line corresponding to this substance, is unsaturated.

The answer is B.

the answer is the

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
