Question

The number of CO2 molecules in a pot are 3..01× 1030 calculate the moles and mass

Answer 1

Answer:

0.04998339422 mole.

Explanation:

given numbers. of molecules are, 3.01 *10^22 so

using the formula:

no. of mole = given no. of molecule /avagadro no.

so, here

no of mole. = 3.01*10´22/ 6.022*10´23

0.04998339422 mole.

The number of CO₂ molecules in a pot are 3.01× 10³⁰ calculate the moles and mass?

Answer:

The number of moles of $CO_{2}$  is equal to $0.499*10^{7}moles$.

The mass of given number of  $CO_{2}$ molecules is $22*10^{7}gmol^{-1}$.

Explanation:

Given the number of $CO_{2}$  molecules in a pot $=3.01*10^{30}$

We know, 1 mole of a gas contains $=6.023*10^{23}molecules$

If  $6.023*10^{23}molecules$  of $CO_{2}$ contain moles $=1 mole$

Then  $3.01*10^{30}$ molecules of $CO_{2}$  contain $=\frac{3.01*10^{30}}{6.023*10^{23}}$

                                                               $=0.499*10^{7}moles$

Molar mass of 1 mole of $CO_{2}$   $=44gmol^{-1}$

Mass of $0.499*10^{7}moles$ of $CO_{2}$  $={44}*{0.499*10^{7}} =22*10^{7}gmol^{-1}$
