Question

in a bank ther are many coins as number of molecules in 1.6 ug og CH4.how many coins are there in a bank​

Answer 1

Answer : The number of coins in a bank are, $6.022\times 10^{16}$

Explanation : Given,

Mass of methane molecule = $1.6\mu g=1.6\times 10^{-6}g$

conversion : $1\mu g=10^{-6}g$

Molar mass of methane molecule = 16 g/mole

First we have to calculate the moles of methane molecule.

$\text{Moles of }CH_4=\frac{\text{Mass of }CH_4}{\text{Molar mass of }CH_4}=\frac{1.6\times 10^{-6}g}{16g/mole}=1\times 10^{-7}mole$

Now we have to calculate the number of coins in a bank.

As, 1 mole contains $6.022\times 10^{23}$ number of coins

So, $1\times 10^{-7}$ mole contains $1\times 10^{-7}\times (6.022\times 10^{23})=6.022\times 10^{16}$ number of coins

Therefore, the number of coins in a bank are, $6.022\times 10^{16}$
