- While heating two different samples of water at sea level, one boils at 102 degrees Celsius and one boils at 99.2 degrees Celsius. Calculate the percent error for each sample from the theoretical 100 degrees Celsius.You are asked to calibrate a 25 mL volumetric pipet. You determine that the temperature of your distilled water is exactly 24.5 degrees Celsius. You carefully determined the mass of a clean dry beaker and found that it was 57.5513 g. You pulled water up to the mark and transferred this to the beaker and found that the new mass was 82.9344 g. What is the actual volume of the pipet? The density of water at 24.5 degrees Celsius is 0.997983 g/mL.calculate the volume occupied by 25.0 g of lead if the density of lead is 11.4g/cm^3 at 25 degrees celsius.
- Dennis obtained a clean, dry stoppered flask. He determined the mass of the flask and stopper to be 32.634 g. He then filled the flask with water and determined the mass of the full stoppered flask to be 59.479 g. Based on the temperature of the water, Dennis found the density of water in the Handbook of Chemistry and Physics to be 0.998730 g/cm3. Calculate the volume of the flask.Convert 38.50 °C to the SI unit for temperature. O 273.15 K O 311.65 K O 101.3 °FConvert 252 K to °C.
