Based on boiling & freezing point of waterTemperature Scales
273 + °C = K
Precise = means shots are close to one another
1. The boiling point of water is 100°C. During an experiment, water came to a boil at 97°C according to the thermometer that was being used. What is the percent error?
2. An experiment was performed to determine the density of water. The results of the experiment showed that water had a density of 1.15 g/mL(real value is 1.0 g/mL). What is the percent error?
3. An experiment was conducted to find the mass of one mole of carbon atoms. The results of the experiment showed that a mole of carbon atoms has a mass of 15.78g. The actual value is 16 grams. What is the percent error?
4. An experiment performed to determine the density of lead yields a value of 10.95 g/cm3. The actual value for the density of lead is 11.342 g/cm3. Find the percent error.
5. Find the percent error in a measurement of the boiling point of bromine if the experimental value is 40.6°C and the actual value is 59.35°C.
