How many moles of carbon do you have in a trillion carbon

Dmitry_Shevchenko [17]

Answer:

$1.7\times 10^{-12}$ moles of carbon

Explanation:

1 trillion = $10^{12}$

Avogadro number :It is the number of particles that are present in 1 mole of substance.

$N_{0} = 6.022\times 10^{23}$

So,

$6.022\times 10^{23}$ atoms = 1 mole carbon

1 atom =

$\frac{1}{6.022\times 10^{23}}$ mole

1 trillion atom =

$\frac{1}{6.022\times 10^{23}}\times 10^{12}$ mole

$1.660\times 10^{-12}$ mol

Two significant figure

$1.7\times 10^{-12}$ moles of carbon

Complete Question

The complete question is shown on the first uploaded image

Answer:

The calculation and filling of the table based on the ratio indicated by the column is shown on the second uploaded image

1 This is True

2 This is False

3 This is False

4 This is True

5 This is True

Explanation:

Based on your calculations, indicate whether each statement is True (T) or False (F):

Considering the first statement

Looking at the question we can see that the first statement is TRUE this because all the three experiment have different initial concentration (3.5,3.0 & 2.6)

Considering the second statement

Looking at table we can see that the second statement is FALSE because

the ratio value of [NO2]/ [N2O4] in all three experiment have different value 1.4 , 1.5 & 1.7 is not a constant value.

Considering the Third statement

Looking at the table we can see that the third statement is FALSE this is because the ratio value of 2[NO2]/ [N2O4] in all three experiment have different value 2.7, 3.0 & 3.3 is not a constant value.

Considering the Fourth statement

Looking at table we can see that the fourth statement is TRUE this is because the ratio value of $[NO2]^{2}/ [N2O4]$ in all three experiment have same value 3.9, 3.9 & 3.9 is a constant value.
