Answer:

4.06*10⁻⁵ g=0.0000406 g

Explanation:

Scientific notation is a quick way to represent a number using powers of base ten.

The numbers are written as a product:

a * 10ⁿ

where:

  • a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a number that is not an integer.
  • n = an integer, which is called an exponent or order of magnitude. Represents the number of times the comma is displaced. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.

In small numbers, where the exponent of ten is negative, the comma must be moved to the left as many positions as the exponent marks, adding zeros between the number and the decimal point.

In this case: 4.06*10⁻⁵ g=0.0000406 g

The analysis of a compound containing K, P and O showed 55 % K, 15 % P and 30 % O, set up the simplest empirical formula of this
Leokris [45]

Answer:

Empirical formula is K₃PO₄.

Explanation:

Given data:

Percentage of K = 55%

Percentage of P = 15%

Percentage of O = 30%

Empirical formula = ?

Solution:

Number of gram atoms of K = 55 / 39.098 = 1.41

Number of gram atoms of P = 15 /30.974= 0.48

Number of gram atoms of O = 30 / 15.999 = 1.88

Atomic ratio:

             K                      :          P                   :         O

           1.41/0.48            :       0.48/0.48        :       1.88/0.48

               3                     :           1                    :            4

K : P : O = 3 : 1 : 4

Empirical formula is K₃PO₄.
