Ethylene glycol, an antifreeze. has a density of 1.11 g\/mL at 20 \u00b0C. <\/p>\n\n\n\n
a) What is the mass, in grams of 452 mL ethylene glycol? <\/p>\n\n\n\n
b) What is the mass in kilograms of 18.6 L ethylene glycol? <\/p>\n\n\n\n
c) What is the volume, in milliliters, occupied by 65.0 g ethylene glycol?<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To solve these problems, we can use the basic density equation:<\/p>\n\n\n\n [ This can be rearranged to solve for mass, volume, or density depending on the given information:<\/p>\n\n\n\n [ Given the density of ethylene glycol as 1.11 g\/mL at 20 \u00b0C, we can now proceed with each part of the question.<\/p>\n\n\n\n We are given the volume (452 mL) and the density (1.11 g\/mL), so we can use the formula for mass:<\/p>\n\n\n\n [ So, the mass of 452 mL of ethylene glycol is 501.72 grams<\/strong>.<\/p>\n\n\n\n First, we need to convert the volume from liters to milliliters (1 L = 1000 mL). So:<\/p>\n\n\n\n [ Now we can calculate the mass using the density formula:<\/p>\n\n\n\n [ To convert grams to kilograms (1 kg = 1000 g):<\/p>\n\n\n\n [ So, the mass of 18.6 L of ethylene glycol is 20.646 kilograms<\/strong>.<\/p>\n\n\n\n We are given the mass (65.0 g) and the density (1.11 g\/mL), and we need to solve for the volume. Using the formula for volume:<\/p>\n\n\n\n [ So, the volume occupied by 65.0 g of ethylene glycol is 58.65 milliliters<\/strong>.<\/p>\n\n\n\n These calculations are based on applying the density formula, using unit conversions when necessary, and ensuring consistent units throughout the problem.<\/p>\n","protected":false},"excerpt":{"rendered":" Ethylene glycol, an antifreeze. has a density of 1.11 g\/mL at 20 \u00b0C. a) What is the mass, in grams of 452 mL ethylene glycol? b) What is the mass in kilograms of 18.6 L ethylene glycol? c) What is the volume, in milliliters, occupied by 65.0 g ethylene glycol?
