Answer:
1.0305 × 10³ kg/m³
Explanation:
A number in scientific notation has the form N × 10^a
where N is a decimal number called the <em>mantissa</em> and a is an integer called the <em>exponent.</em>
We must have 1 ≤ N < 10
Step 1. <em>Determine the mantissa
</em>
Move the decimal place to the left to create a new number between 1 and 10.
1030.5 ⟶ 1.0305; N = 1.0305
===============
Step 2. <em>Determine the exponent</em>.
The exponent is the number of times you moved the decimal to get the mantissa.
You moved the decimal three places to the left, so the exponent a = 3.
===============
Step 3. <em>Write the number in scientific notation
</em>
1030.5 = N × 10^a = 1.0305 × 10³
The density in scientific notation is 1.0305 × 10³ kg/m³.
