The accepted value for the density of liquid mercury is 13.5336 g/ml. four scientists measure the density of liquid mercury in their individual laboratories. the most accurate measurement is made by dr. chopra, who measures 13.487 g/ml. dr. thompson, who measures 13.5 g/ml. dr. smith, who measures 13.54 g/ml. dr. tyler, who measures 13.9336 g/ml.

The most accurate measurement was made by Dr. Smith

Explanation:

The accepted value for the density of liquid mercury = 13.5336 g/mL

The most accurate measurement made by the scientists will be taken which has the minimum percentage error.

Formula o

Experimental value = 13.487 g/mL

% error = 0.344%

Experimental value = 13.5 g/mL

% error = 0.248 %

Experimental value = 13.54 g/mL

% error = 0.0472%

Experimental value = 13.9336 g/mL

% error = 2.955 %

As, from the calculate percentage error. the % error by Dr. Smith is the least. Hence, the most accurate measurement for the density of liquid mercury will be 13.54 g/mL

3 hours because it is a decent distance.

the answer would be c
