I am unsure if this is correct, but this might be the whole section:
- The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. <em>Answer: </em><em>3.60 </em><em>cm</em>
- Divide by two to find the radius. Maintain significant figures. <em>Answer: </em><em>1.80 </em><em>cm</em>
- Substitute the radius into the formula A = πr² to find the area of the top of the syringe. Maintain significant figures. <em>Answer: </em><em>10.2 </em><em>cm²</em>
Answer:
9.61 % error
Explanation:
The formula for percent error is as follows:
% error = (experimental value - theoretical value) ÷ theoretical value × 100%
So to calculate the percent error all you have to you is plug in your values.
% error = (4.45cm - 4.06cm)/4.06 × 100%
= 0.39/4.06 × 100%
= 0.0961 × 100%
= 9.61 % error

Answer:
Explanation:
Given the amount of heat absorbed and the amount of substance in moles, we may calculate the heat of vaporization. Heat of vaporization is defined as the amount of heat per 1 mole of substance required to evaporate that specific substance.
Based on the value of heat of vaporization, we will identify the substance. Firstly, let's calculate the heat of vaporization:
Secondly, let's use any table for heat of vaporization values for substances. We identify that the heat of vaporization of is 18.7 kJ/mol
