**Educational Content: Calculating Moles of Gas****Problem Statement:**A sample of methane gas (CH₄) is collected at a pressure of 0.638 atm and a temperature of 279 K. It occupies a volume of 695 milliliters. Calculate the number of moles of CH₄ gas in the sample.**Instructions:**- Use the ideal gas law formula: PV = nRT - P = pressure (atm) - V = volume (liters) - n = moles of gas - R = ideal gas constant (0.0821 L·atm/mol·K) - T = temperature (Kelvin)- Convert the volume from milliliters to liters by dividing by 1000. - Rearrange the formula to solve for n (moles): n = PV / RT**Interactive Components:**- Enter your calculated value in the provided box and submit your answer.- You have multiple attempts to ensure understanding.- Use the "References" section for important values or additional help if needed.**Options:**- [Submit Answer]- [Retry Entire Group] (9 more attempts remaining)For further assistance, contact your instructor using the "Email Instructor" feature.**Note:** This exercise is part of a series from Cengage Learning's OWLv2 platform, designed to enhance your understanding of gas laws and their applications in real-world scenarios.

We will use the Ideal gas equation to calculate the mol of CH4 PV=nRT R=8.314 JK-1mol-1 or…

Select all the statements that apply to Charles's law. Charles's law relates gas volume and temperature in Kelvin. The volume of as is proportional to its temperature in degrees Celsius or Kelvin. The volume of a gas decreases as temperature increases if the gas is kept at a constant pressure and fixed amount. ✔The volume of a gas increases as temperature increases if the gas is kept at constant pressure and fixed amount.
