Answer: The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
Explanation:
Scientific notation is defined as 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 : 5000 is written as [tex]5.0\times 10^3[/tex]
According to avogadro's law, 1 mole of every gas contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles, occupy 22.4 L at STP and weighs equal to its molecular mass.
131.29 g of Xe occupy = 22.4 L at STP.
Thus 213.62 g of [tex]Xe[/tex] occupy = [tex]\frac{22.4}{131.29}\times 213.62=36.45L[/tex] at STP.
Scientific notation = [tex]3.645\times 10^1L[/tex]
The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
