Human teeth are made up of four different types of tissues.
Hi!
Let me complete the question for you.
Trial Count Percent Error Trial 1 0,05
Trial 2 0,02
Trial 3 0,01
The most accurate value is the one From
Trial 3
Percent Error is a measure of the difference between the experimental value and a theoretical one. The equation for calculating the percent error is shown below:
Results are more accurate as the Percent Error is lower, so as Trial 3 has the lowest percentage error, the result of it would be the most accurate.
Have a nice day!
1) A 45.7 g sample of glass was brought to thermal equilibrium with boiling water and then transferred to 250.0 g of water that was at 22.5 °C. This combination reached thermal equilibrium at 24.2 °C. What is the specific heat capacity of glass?
2) What mass of silver at 100.0 °C, when added to 150.0 g of water at 21.0 °C, would raise the water’s temperature to 24.0 °C ?
3) The molar heat of fusion of H2O is 6.1 kJ/mole. What amount of energy would be needed to melt 376 g of ice at 0.0 °C?
