Question

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

Answer 1

The amount of gold in decigrams if 450 micrograms is needed is 4.5 × 10-³ decigrams.

How to convert micrograms to decigrams?

According to this question, 450 micrograms of a sample of gold is needed but we only have a mass balance that measures in decigrams.

This means that we are to convert the amount of gold you need to decigrams by comparing the exponents.

The conversion factor of micrograms to decigrams is as follows:

1 micrograms = 1 × 10-⁵ decigrams

This means 450 micrograms is equivalent to 450 × 1 × 10-⁵ = 4.5 × 10-³ decigrams

Therefore, the amount of gold in decigrams if 450 micrograms is needed is 4.5 × 10-³ decigrams.
