Since 1965, dimes are composed of copper with 25% nickel on the outside. A Roosevelt Type dime (1946 to 1964), designed by John R Sinnockis, is composed of 90.0% silver and 10.0% copper. The composition changed when the dime cost more in silver than it was worth. A 1963 dime is weighed on ten different balances, and the mass is recorded.

Using your measured density (8.81g/cm3), and the knowledge that %Zn + %Sn = 5.00%, calculate the %Sn in these pennies. copper= 95% ,density = 8.96zinc = 5%, density = 7.13tin = density 7.31
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.
