Answer:
1.015 × 10^3 kg/m³
Step-by-step explanation:
We are given;
- Density of a mixture as 1015.3 kilograms per cubic meter
Required to write the density using scientific notation.
We need to first understand what is scientific notation.
- Scientific notation is a method used to write very large numbers or very small numbers in the form of A × 10^n, where A is a value between 1 and 10 and n is a positive or a negative integer.
Examples of values written in scientific notation.
- For example, a very large value such as 20000000 can be written as 2.0 × 10^7, the value of n is positive because the decimal places has been moved 7 places to the left.
- While a value that is very small such as 0.0000000234 can be written as 2.34 × 10^-8, the value of n is negative since the decimal place has been moved 8 places to the right.
In our case,
1015.3 will be written as 1.015 × 10^3
Therefore,
Using scientific notation the density is 1.015 × 10^3 kg/m³
