Question

How many moles are there in 2.43e+21 molecules of carbon dioxide?

Answer 1

Moles of Carbon dioxide : n = 4.037 x 10⁻³

Further explanation

Given

2.43 x 10²¹ molecules of Carbon dioxide

Required

Moles

Solution

1 mol = 6.02 x `10²³ particles(molcules, atoms, ions)

Can be formulated :

N = n x No

n = moles

No = Avogadro's number 6.02 x `10²³

moles of Carbondioxide :

n = N/No

n = 2.43 x 10²¹ / 6.02 x `10²³

n = 4.037 x 10⁻³
