How many moles of gold are equivalent to 1.204 × 1024 atoms?

LUCKY_DIMON [66]

Explanation:

It is known that the value of Avogadro's number is $6.022 \times 10^{23}$ .

Therefore, calculate moles of gold atoms as follows.

Moles of gold atom = $\frac{given number of atoms}{Avogadro's number}$

= $\frac{1.204 \times 10^{24}}{6.022 \times 10^{23}mol^{-1}}$

= $0.199 \times 10$ mol

= 1.99 mol

Thus, we can conclude that 1.99 mol of gold atoms are equivalent to $1.204 \times 10^{24}$ atoms.

¿Cuántos gramos de H2O habrá en 3,0115x1023 moléculas de agua?

jolli1 [7]

Answer : The weight of water is 9 g

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text{avogadro's number}}=\frac{3.0115\times 10^{23}}{6.023\times 10^{23}}=0.5moles
$

1 mole of water $(H_2O)$ weighs = 18 g

0.5 moles of water $(H_2O)$ weighs = $\frac{18}{1}\times 0.5=9g$

Thus the weight of water is 9 g
