You need a 450-microgram sample of gold, but you only have a mass balance that measures in decigram. Convert the amount of gold you need to decigrams by comparing the exponents. Provide your answer in scientific notation.

Acylindrical specimen of a nickel alloy having an elastic modulus of 207 gpa (30 × 106psi) and an original diameter of 10.2 mm (0.40 in.) experiences only elastic deformation when a tensile load of 8900 n (2000 lbf) is applied. compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in.)
