First, you need to check the solubility of salt table to get the solubility of KNO3(s) at 50℃. The solubility is 84g/100g which means you need 84 g KNO3 dissolving in 100 g water to make saturated solution.

The solubility of substance depends upon the temperature. In present case, the solubility of KCl is 84g/100g at <span>50.oC. 

This means that, maximum 84g of KCl can be dissolved in 100g of water (at </span>50.oC) to form solution. This solution is referred as saturated solution. 

Thus, 84g of <span>KNO3 must be dissolve in 100 grams of water to form a saturated solution at 50 oC.</span>

How many mL will a 0.205 mole sample of He occupy at 3.00 atm and 200 K? Report your answer to the nearest mL.
Tcecarenko [31]

1.1214 mL will a 0.205-mole sample of He occupy at 3.00 atm and 200 K.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Using equation PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 3.00 atm

V= ?

n=0.205 mole

R= 0.082057338 \;L \;atm \;K^{-1}mol^{-1}

T=200 K

Putting value in the given equation:

\frac{nRT}{P} =V

V= \frac{0.205 \;mole\;0.082057338 \;L \;atm \;K^{-1}mol^{-1} X 200}{3 \;atm}

V= 1.1214 mL
