Calculate the volume of the gas, in liters, if 1.35 mol

Alina [70]

Answer:

22.8 L

Explanation:

Step 1: Given data

Moles of the gas (n): 1.35 mol

Pressure of the gas (P): 1.30 atm

Temperature (T): -6°C

Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15 = -6 + 273.15 = 267 K

Step 3: Calculate the volume of the gas

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 1.35 mol × (0.0821 atm.L/mol.K) × 267 K / 1.30 atm

V = 22.8 L

32P has a half life of 14.0 days. If you order 60.0 grams of 32P and it took 46.7hrs from the time it was made to the time it wa

8090 [49]

Answer:

$[A_t]=54.5\ g$

Explanation:

Given that:

Half life = 14.0 days

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$k=\frac{\ln2}{t_{1/2}}$

$k=\frac{\ln2}{14.0}\ days^{-1}$

The rate constant, k = 0.04951 days⁻¹

Initial concentration [A₀] = 60.0 g

Time = 46.7 hrs

Considering, 1 hr = 0.041667 days

So, time = 1.9458 days

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t

So,

$[A_t]=60.0\times e^{-0.04951\times 1.9458}\ g$

$[A_t]=54.5\ g$
