Answer to Question #35421 in Physical Chemistry for Kristen Woods

Question

Use the 5-step method and be sure to include units where appropriate. Round your answers to the correct number of significant digits.
Adjust the density formula and solve the problems below:

The density of silver is 110.49 g/cm3. If a sample of pure silver has a volume of 112.993 cm3, what would the mass?

Answer 1

d(Ag) = 110.49 g/cm3 – 5 significant digits
V(Ag) = 112.993 cm3 – 6 significant digits

For multiplication the result should contain as many significant digits as in the smallest measured number.

m = d*V
m(Ag) = 110.49 g/cm3*112.993 cm3 = 12485 g – 5 significant digits.
