Question

Represent 0.00563 mg as a number between 0.1 and 1000 using an appropriate prefix Express your answer to three significant figures and include the appropriate units. 2 ? "! HAR 0.00563 mg = 5.63 . 10-3 O mg

Answer 1

5.63 microgram (μg)

Step-by-step explanation:

Here mass is given in miligram

Some of the prefixes of the SI units are

1 gram = 10⁻³ kilogram

1 milligram = 10⁻⁶ kilogram

1 microgram = 10⁻⁹ kilogram

1 nanogram = 10⁻¹² kilogram

1 microgram = 10⁻³ miligram

The number is 0.783

Here, the only solution where the number of significant figures is three is microgram. If any other prefix is chosen then the significant figures will increase.

`1\ miligram = 1000\ microgram`

`\\\Rightarrow 0.00563\ miligram=0.00563* 1000\ microgram\\ =5.63\ microgram`

So, 0.00563 miligram = 5.63 microgram
