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

help asap show work | a gas with a volume of 13L at a pressure of 197 kPA is allowed to expand to a volume of 23L. what is the p

Lera25 [3.4K]

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

$P_2 = \frac{P_1V_1}{V_2} \\$

We have

$P_2 = \frac{13 \times 197000}{23} = \frac{2561000}{23} \\ = 111347.826...$

We have the final answer as
