Question

The average radius of a molecule of lysozyme, an enzyme in tears, is 1430. pm. What is its radius in centimeters (cm)? (Enter your answer in scientific notation.)

Answer 1

Answer:

1.43 ×10⁻⁷ cm

Explanation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

Radius of molecule of lysozyme:

1430 pm

In centimeter:

1430/10¹⁰

1.43 ×10⁻⁷ cm

The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10 such as, 1430 pm.
