While working in the laboratory, a student finds the density of a piece of pure aluminum to be 2.85 g/cm3. The accepted value for the density of aluminum is 2.699 g/cm3. What is the student's percent error?
A student experimentally determines the specific heat of water to be 4.29 J/g x Co. He then looks up the specific heat of water on a reference table and finds that is is 4.18 J/g x Co. What is his percent error?
A student takes an object with an accepted mass of 200.00 grams and masses it on his own balance. He records the mass of the object as 196.5 g. What is his percent error?
The true value of the density of water at a particular temperature is 1.00 g/ml. If a student experimentally determines the density of water at this temperature to be 1.17 g/ml, what is her experimental error?
A student experimentally determines the molar volume of a gas to be 21.9 L/mole. Calculate the student's percent error if the accepted value for the molar volume of a gas is 22.4 L/mole.
A scientist finds the density of carbon dioxide to be 1.72 g/L at STP. If the accepted value for the density of carbon dioxide at STP is 1.98 g/L, what is his percent error?
A student finds the density of carbon monoxide to be 1.62 g/L at STP. If the accepted value for the density of carbon monoxide at STP is 1.25 g/L, what is the % error?
The true value of the heat of fusion of ice is 79.72 cal/g. A student experimenting with the heat of fusion of ice finds a value of 84.00 cal/g. Determine the percent error.
A student finds the specific heat of water to be 4.29 J/g x C o . Assuming the true value is 4.18 J/g x C o , calculate his percent error.
A student measures the mass and volume of a piece of copper in the lab and calculates the density of the metal to be 8.37 g/cm3. She then finds the accepted value for the density of copper is 8.92 g/cm 3 . What would be the student's percent error
