Question

The mass of one cup of water is 0.236 kilograms. Use scientific notation to represent the mass of one cup of water.

Answer 1

Answer : The mass of one cup of water represented in scientific notation as, $2.36\times 10^{-1}Kg$

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

8000 is written as $8.0\times 10^3$

779.9 is written as $7.799\times 10^{-2}$

In this examples, 8000 and 779.9 are written in the standard notation and $8.0\times 10^3$  and $7.799\times 10^{-2}$  are written in the scientific notation.

As we are given the mass of one cup of water is, 0.236 Kg

It is written in the scientific notation as, $2.36\times 10^{-1}Kg$

Hence, the mass of one cup of water represented in scientific notation as, $2.36\times 10^{-1}Kg$

Answer 2

2.36 x 10^-1
You move the decimal to right behind the first significant digit and the exponent on the 10 is how many places you moved that decimal. You can type it into a calculator to check it as well if you're not sure.
