The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
To find the weight of 1 gallon of pure oxygen gas, we need to follow these steps:<\/p>\n\n\n\n
Step 1: Convert the volume of oxygen from gallons to liters<\/h3>\n\n\n\n
We know that 1 gallon = 3.78 liters. So, the volume of oxygen gas we are dealing with is:Volume in liters=1 gallon\u00d73.78 L\/gallon=3.78 L\\text{Volume in liters} = 1 \\text{ gallon} \\times 3.78 \\text{ L\/gallon} = 3.78 \\text{ L}Volume in liters=1 gallon\u00d73.78 L\/gallon=3.78 L<\/p>\n\n\n\n
Step 2: Use the density of oxygen gas to calculate the mass<\/h3>\n\n\n\n
The density of oxygen gas is given as 0.00111 g\/cm\u00b3 at room temperature and 1 atm pressure. To proceed, we need to convert liters to cubic centimeters (cm\u00b3), since the density is given in g\/cm\u00b3.<\/p>\n\n\n\n
    \n
  • 1 liter = 1000 cm\u00b3.<\/li>\n<\/ul>\n\n\n\n
    Thus, the volume of oxygen in cubic centimeters is:Volume in cm3=3.78 L\u00d71000 cm3\/L=3780 cm3\\text{Volume in cm}^3 = 3.78 \\text{ L} \\times 1000 \\text{ cm}^3\/\\text{L} = 3780 \\text{ cm}^3Volume in cm3=3.78 L\u00d71000 cm3\/L=3780 cm3<\/p>\n\n\n\n
    Now, we can calculate the mass of oxygen using the formula:Mass=Density\u00d7Volume\\text{Mass} = \\text{Density} \\times \\text{Volume}Mass=Density\u00d7Volume<\/p>\n\n\n\n
    Substituting the values:Mass=0.00111 g\/cm3\u00d73780 cm3=4.1978 g\\text{Mass} = 0.00111 \\text{ g\/cm}^3 \\times 3780 \\text{ cm}^3 = 4.1978 \\text{ g}Mass=0.00111 g\/cm3\u00d73780 cm3=4.1978 g<\/p>\n\n\n\n
    So, the mass of 1 gallon of oxygen gas is approximately 4.20 grams.<\/p>\n\n\n\n
    Step 3: Convert grams to kilograms<\/h3>\n\n\n\n
    Since 1 kilogram = 1000 grams, we convert the mass to kilograms:Mass in kg=4.20 g1000=0.0042 kg\\text{Mass in kg} = \\frac{4.20 \\text{ g}}{1000} = 0.0042 \\text{ kg}Mass in kg=10004.20 g\u200b=0.0042 kg<\/p>\n\n\n\n
    Step 4: Convert kilograms to pounds<\/h3>\n\n\n\n
    Finally, we use the conversion factor: 1 kg = 2.2 lbs.Mass in lbs=0.0042 kg\u00d72.2 lbs\/kg=0.00924 lbs\\text{Mass in lbs} = 0.0042 \\text{ kg} \\times 2.2 \\text{ lbs\/kg} = 0.00924 \\text{ lbs}Mass in lbs=0.0042 kg\u00d72.2 lbs\/kg=0.00924 lbs<\/p>\n\n\n\n
    Final Answer:<\/h3>\n\n\n\n
    The weight of 1 gallon of pure oxygen gas is approximately 0.00924 pounds<\/strong>.<\/p>\n\n\n\n
    Explanation:<\/h3>\n\n\n\n
    The process involves converting the given volume (1 gallon) to liters, converting liters to cubic centimeters, using the density to calculate the mass in grams, and then converting grams to pounds. The small mass of oxygen gas illustrates how light gases can be compared to liquids or solids.<\/p>\n\n\n\n
