Answer:
150
Explanation:
We can <u>find the equivalent number of O₂ molecules for 100 molecules of CO₂</u> using a <em>conversion factor containing the stoichiometric coefficients of the balanced reaction</em>, as follows:
150 molecules of O₂ would produce 100 molecules of CO₂.
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
According to avogadro's law, 1 mole of every gas contains avogadro's number 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 occupy =
at STP.
Scientific notation =
The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
