4 0

<em>Answer:</em>

  • The option C is correct.
  • CH4N, 90g, C3H12N3.

<em>Explanation:</em>

                    <em>Option C:</em>

  • The molecular formula is C3H12N3.
  • If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
  • The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

                <em>Option A :</em>

  • In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.

              <em>Option B:</em>

  • In option B, molecular formual is not valid.
  • It should be as C6H16O2

What is (3.11*10^-5)-(4.21*10^-2)
Reptile [31]

Taking into account the scientific notation, the result of the subtraction is -4.20689×10⁻².

<h3>Scientific notation</h3>

Scientific notation is a quick way to represent a number using powers of base ten, where 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 non-integer number.
  • n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.

<h3>Subtraction in scientific notation</h3>

When the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is -2.

Then all the values ​​are expressed as a function of the base 10 exponent with the highest exponent. In this case: 3.11×10⁻⁵= 0.00311×10⁻²

Taking the quantities to the same exponent, all you have to do is subtract what was previously called the number "a". In this case:

0.00311×10⁻² - 4.21×10⁻²= (0.00311 - 4.21)×10⁻²= -4.20689×10⁻²

Finally, the result of the subtraction is -4.20689×10⁻².
