CHEMISTRY Calculating Density Density is the compactness of matter. Density describes the quantity of matter (mass) per unit of volume (3-dimensional space). Density is calculated as the mass of the matter divided by volume. The symbol for density is Greek letter rho (p). The units for mass are in grams (g) and the units for volume is cubic centimeter (cm³). It should be noted that 1 cm³ is equal to 1 ml of volume. 1 cm³= 1 ml. The units for density are g/cm³. Part 1 Determine the density of the new liquid materials created in the Secret Density Research Laboratory. Type the value (no units) of the density into the boxes in the density column. Report density to the 2nd number after the decimal. Use a zero to the lef of the decimal for values less than 1.00. Examples: 2.35, 0.75, 1.90 Material name Harrisonite Waltonium Kellese Wheelernone Osborneum Popebrillium Mass (g) 430 590 260 m P=V 620 380 510 Volume (cm³) 537 454 236 364 633 340 Density (g/cm³) SAMSUNG

25) If time could be expressed in ppm, how many seconds per year would be 2.5 ppm?

Errors of different varieties may arise throughout the course of an experiment. Below, match the different types of errors with their corresponding definitions. Group of answer choices Errors that have an equal chance to be positive or negative. These errors will arise because it is impossible to make any measurement completely exact. Errors that will have a consistent directional bias every time the experiment is carried out. These errors tend to always be positive or negative, meaning over or underestimating, respectively, the true value of the measurement due to experimental limitations. An error that is within the direct control and/or caused by a mistake from the chemist. Options Random error Systematic error Human mistake
