Apool is 44.6 m long and 27.6 m wide. if the average depth of water is 8.80 ft, what is the mass (in kg) of water in the pool? enter your answer in scientific notation.

Explanation:

The form of the pool may be approximated to a reactangular prism with height equal to the average depth of water.

1) Dimensions:

2) Volume formula

3) Unit conversions

Convert 8.80 ft to meters:

4) Volume calculation

Substitute the numbers in the formula:

5) Mass of water:

6) Scientific notation

Choose the correct number of significant figures:

The mass must be expressed as a power of ten. The mantissa contains only the significant digits, and the number before the decimal point can only have one digit 1 through 9.

1 is the answer to this problem

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
