Question

since molar mass of carbon is 12 grams then 48 grams of carbon atoms would be equal to mass

Answer 1

Answer:

Explanation:

Mass of one mole of carbon atom =12 g

A mole of carbon contains 6.022×1023 atoms.

Hence, mass of 6.022×1023 atoms of carbon =12 g  

Mass of 1 atom of carbon =  12/6.022×10^23

​   =1.993×10  ^−23 g

Answer 2

48 g $= 2.4088\times 10^{24}$atoms of carbon

Explanation:

Given:

• The molar mass of carbon atoms =  12 grams

It means 12 g is the mass of Avogadro's number of particles.

or,

$12 g = 6.022\times 10^{23}$ atoms of carbon

So,

$1 g = \frac{6.022\times 10^{23}}{12}$ atoms of carbon

$48 g = \frac{6.022\times 10^{23}}{12}\times 48$  atoms of carbon

$48 g = 24.088\times 10^{23}}$ atoms of carbon

$48 g = 2.4088\times 10^{24}}$ atoms of carbon

or 48 g of carbon atoms are four times the molar mass of carbon

(Assuming the question is "since molar mass of carbon is 12 grams then 48 grams of carbon atoms would be equal to_____number of carbon atoms")
