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

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 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.

the answer is c i believe

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
