Question

find out the number of particles of a 5
moles of methane gas​

Answer 1

Explanation:

1) 1 mole methane contain 6.023 x 10²³ particles

so, 5 mole containe 6.023 x 10²³ x 5 particles

= 30.115 x 10²³ particles

Answer 2

Answer:

the answer = 30.1010 x $10^{23}$

Explanation:

let us first write teh given quantities:-

number of particles ( N ) = we have to find out ( ? )

number of moles = 5 moles

molar mass of methane gas = $CH_{4}$ = 12 + ( 1*4 )

                                                          = 12 + 2

                                                          = 16g

Now, the formula to find the number of molecules is N = n * $N_{0}$

where n = 5 moles, $N_{0}$ = 6.022 * $10^{23}$

N = n * $N_{0}$

N = 5 * 6.022 * $10^{23}$

N = 30.1010 x $10^{23}$

that's all. good luck
