Sample of gas initially occupies 4.25 L at a pressure of 0.850 atm at 23.0°C. What will the volume be if the temperature is chan
Aliun [14]

Answer:  2.34 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 0.850 atm

P_2 = final pressure of gas = 1.50 atm

V_1 = initial volume of gas = 4.25 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 23.0^oC=273+23.0=293.0K

T_2 = final temperature of gas = 11.5^oC=273+11.5=284.5K

Now put all the given values in the above equation, we get:

\frac{0.850\times 4.25}{293.0K}=\frac{1.50\times V_2}{284.5}

V_2=2.34L

Thus the final volume will be 2.34 L

approximately how many grams of sodium chloride (NaCl) are required to prepare 500. mL of 3.00 M solution
matrenka [14]
First convert mL to L:
(500. mL)/(1000L) = .500L

Then convert molarity to moles:
(3.00M)(.500L) = 1.5mol NaCl

Then convert moles of NaCl to grams of NaCl by multiplying it by its molar mass:
(1.5mol NaCl)(58.44g/mol NaCl) = 87.66g NaCl are needed
