Question

Calculate the mass of $$12.0\times 10^{14}$$ atoms of hydrogen.


A
6.023×1023 g

B
12×1014 g
loader
C
1.99×109 g

D
9.33×1022 g

Solution

The correct option is B $$1.99\times 10^{-9} $$ g
Mass of $$6.02\times 10^{23}$$ atoms of hydrogen = $$1$$ g
Therefore mass of $$1$$ atom of hydrogen = $$\dfrac{1}{6.02\times 10^{23}}$$ g
$$\therefore$$ Mass of $$12\times 10^{14}$$ atoms of hydrogen = $$\dfrac{12\times 10^{14}}{6.02\times 10^{23}}$$ = $$1.99\times 10^{-9}$$g
