A sample of unknown liquid is weighed in a graduated cylinder and the mass is 130.6g....
An empty graduated cylinder weighs 56.90 g. A student puts 24.6 mL of an unknown liquid into the cylinder and the mass of the cylinder plus the liquid equals 98.47 g. What is the density of the unknown liquid (in g/mL)?
An empty graduated cylinder has a mass of 31.760 g. 50.0 mL of an unknown liquid are added and the mass increases to 71.810 g. What is the density of the unknown liquid?

1)The density of the unknown liquid with the volume of 13.3 mL and a mass of 8.86 g is _______________ g/mL . 2) Describe how you can use the graduated cylinder to determine the volume of a small, irregularly-shaped metal. 3) What safety precaution should you take when adding the irregularly-shaped metal into the glass graduated cylinder?
10. a) Report the volume (in mL) of liquid inside the graduated cylinder by reading the bottom of the meniscus (curved surface). 36.5 mL . b) What is the mass (in grams) of the liquid (d = 21.7 dg/ce) inside 881 the 50 mL graduated cylinder? de 88.188 g A ?g 50 mL graduated cylinder c) If all of the liquid inside the graduated cylinder was poured into the glass cup, what will the combined mass (in g) of both...
A student performed a series of measurements (volume/mass) of an unknown liquid in order to determine its density. Using a graduated cylinder, the student added an amount of unknown liquid to the graduated cylinder, then recorded the mass and volume of the liquid. The student repeated the process several times, adding more liquid each time and recording the mass and volume. The student plotted the data (mass on y-axis, volume on x-axis). The resulting data table and graph looked like...
The mass of a sample is 45g. The original volume recorded in a graduated cylinder is 25mL. The volume recorded after the sample is placed in the cylinder is 40mL. Calculate the density of the sample. O 3.0 g/cm3 O 0.3 g/cm3 O 1.5 g/cm3 O 5.3 g/cm3
. If you have a grad cylinder which weighed 78.35 g when empty, and you filled it to the 26.5 mL mark with carbon tetrachloride (CCl4 (liq)), with a density of 1.61 g/mL, calculate the mass of the cylinder with the liquid.
4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value.
