A sample of helium gas occupies 355ml at 23°c. if the container the he is in is expanded to 1.50 l at constant pressure, what is
ss7ja [257]

Answer: The final temperature would be 1250.7 K.

Explanation: We are given a sample of helium gas, the initial conditions are:

V_{initial}=355mL=0.355L  (Conversion factor: 1L = 1000 mL)

T_{initial}=23\°C=296K (Conversion Factor: 1° C = 273 K)

The same gas is expanded at constant pressure, so the final conditions are:

V_{initial}=1.50L

T_{initial}=?K

To calculate the final temperature, we use Charles law, which states that the volume of the gas is directly proportional to the temperature at constant pressure.

V\propto T

\frac{V_{initial}}{T_{initial}}=\frac{V_{final}}{T_{final}}

Putting the values, in above equation, we get:

\frac{0.355L}{296K}=\frac{1.50L}{T_{final}}

T_f=1250.7K

(d) If you have 9.44 g of NazPO4, how many grams of AgNO, will be needed for complete
AlladinOne [14]

30.6 g of AgNO₃

Explanation:

We have the following chemical reaction:

Na₃PO₄ + 3 AgNO₃ → Ag₃PO₄ +  3 NaNO₃

Now we calculate the number of moles of  Na₃PO₄:

number of moles = mass / molecular weight

number of moles of Na₃PO₄ = 9.44 / 164 = 0.06 moles

Now we formulate the following reasoning:

if        1 mole of Na₃PO₄ will react with 3 moles of AgNO₃

then  0.06 moles of Na₃PO₄ will react with X moles of AgNO₃

X = (0.06 × 3) / 1 = 0.18 moles of AgNO₃

mass = number of moles × molecular weight

mass of AgNO₃ = 0.18 × 170 = 30.6 g
