for number less than 0.1, such as 0.06, the zeros to the right of the decimal point but before the first nonzero digit
qaws [65]

For the number less than 0.1 such as 0.006, the zeroes to the right of the decimal point but before the first non zero digit show the decimal place of the first significant digit.

  • The number that is given as digits is established using significant figures.
  • Any two non-zero digits that are separated by a zero are significant figure.
  • Every zero that is both to the right and left of a non-zero digit and the decimal point is not significant figure.
  • The quantity of significant figures frequently reveals the degree of measurement accuracy. From the first non-zero digits in the figure, we may determine the number of significant figures.

There is only one significant figure in the provided number 0.06. The decimal place of the first digit is indicated by the zeros that appear to the right of the decimal point but before the first non-zero digit.

2. Why was it important to examine both the color and the streak of your minerals? Think about streak and explain why it’s calle
Delicious77 [7]
It is important to examine both the colour and the streak of a mineral because the streak may be completely different from the colour of the hand specimen.
The streak of a mineral is the color it possesses after it has been grounded to a fine powder. The streak test has to be done on minerals because it is a more reliable way of identifying a mineral with its color.<span />

Number of moles = 8.3 x 10⁻¹³

<h3>Further explanation </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance

1 mol = 6.02.10²³  particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's =  6.02.10²³

5 x 10¹¹ atoms of Silver :

\tt mol=\dfrac{5\times 10^{11}}{6.02\times 10^{23}}=8.3\times 10^{-13}

Molar Mass = Mass ÷ Mole

                   =  0.406 g ÷ 0.00105 mol

                   =  386.67 g/mol

∴ molar mass of cholesterol = 386.67 g/mol
