Final answer:
A regular bottle of wine with 12% alcohol by volume contains approximately 5 servings of wine, with each serving being 5 ounces. Moderate consumption is defined as up to one drink per day for women and up to two drinks per day for men.
Explanation:
The question seems to be asking about how many standard servings of wine there are in a bottle with 12% alcohol by volume. The information related to the molar mass of ethanol and its density is useful for understanding the composition of wine but not directly relevant to the number of servings. To determine the number of servings, we can refer to health guidelines. Generally, a serving of wine is considered to be 5 ounces (approximately 150 mL). Since a standard bottle of wine is 750 mL, the math is quite straightforward: 750 mL divided by 150 mL per serving equals 5 servings per bottle.
However, it is important to note that individual serving sizes can vary based on factors such as personal health, dietary needs, and legal drinking age recommendations. Moderate alcohol consumption is defined as up to one drink per day for women and up to two drinks per day for men.
A regular bottle of 12% alcohol by volume wine is equivalent to 12% ethanol by volume. Ethanol has a molar mass of 46.06 g/mol. To find the moles of ethanol present in a 750-mL bottle of wine, we need to convert the volume of wine to mass using its density and then use the molar mass to convert the mass to moles.
First, we calculate the mass of the wine using its volume and density:
Mass = Volume x Density
Mass = 750 mL x 0.789 g/mL
Mass = 591.75 grams
Then, we can calculate the moles of ethanol:
Moles = Mass / Molar Mass
Moles = 591.75 g / 46.06 g/mol
Moles = 12.83 moles
Therefore, a regular bottle of 12% alcohol by volume wine contains approximately 12.83 moles of ethanol.
