Question

The density of a mixture measures 1030.5 kilograms per cubic meter. Use scientific notation to represent the density of the mixture.

PLZZZZ HURRYYYY

Answer 1

The formula for density = mass/volume

So the units are gcm^3

So multiply by 1000 to get into grams - 1030500

Add units

1030500gcm^3

Answer 2

1.0305 × 10³ kg/m³

Step-by-step explanation:

A number in scientific notation has the form N × 10^a

where N is a decimal number called the mantissa and a is an integer called the exponent.

We must have 1 ≤ N < 10

Step 1. Determine the mantissa

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. Determine the exponent.

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. Write the number in scientific notation

1030.5 = N × 10^a = 1.0305 × 10³

The density in scientific notation is 1.0305 × 10³ kg/m³.
