A 410 L volume of nitrogen gas is cooled from 61 C to -25 C. What is the volume of the nitrogen at the lower temperature if all
Lena [83]

Answer:

304.5\text{L}

Explanation:

Here, we want to get the volume of the nitrogen gas at the lower temperature

From Charles' law, we know that volume and temperature (in Kelvin) are directly proportion

The mathematical relationship is:

\frac{V_1}{T_1}\text{ = }\frac{V_2}{T_2}

Where:

V1 is the initial volume which is 410 L

V2 is the final volume which is unknown

T1 is the initial temperature which we will convert to Kelvin by adding 273.15 K, we have it as 61 + 273.15 = 334.15 K

T2 is the final temperature which we have to convert to Kelvin by adding it to 273.15K : We have that as -25 + 273.15 = 248.15 K

Substituting the values, we have it that:

\begin{gathered} \frac{410}{334.15}\text{ = }\frac{V_2}{248.15} \\  \\ V_2\text{ = }\frac{248.15\text{ }\times410}{334.15} \\  \\ V_2\text{ = 304.5 L} \end{gathered}

Calculate the mass of sodium acetate trihydrate required to make 100. ml of a 0.100 m solution. as part of your preparation for
vova2212 [387]

Required moles of CH₃COONa.3H₂O = Molarity x Volume of solution in L

                                                            = 0.100 M x (100.0 mL)

                                                            = 0.100 M x 0.100 L

                                                            = 0.01 mol

Required mass of CH₃COONa.3H₂O = Required moles x Molar mass

                                                            = 0.01 mol x (136.08 g / mol)                                                                              = 1.3608 g
