Answer 1

Answer on Question #50319, Chemistry, Other

What would be the mass of $2.41 \times 10^{24}$ formula units of barium hydroxide?

Solution:

Barium hydroxide is $\mathrm{Ba(OH)_2}$

$M_r = 171.34\ \mathrm{g/mol}$

$N_A = 6.02 \times 10^{23}\ \mathrm{mol}^{-1}$

$$n = \frac{N}{N_A} = \frac{m}{M_r}$$ $$m = \frac{M_r \times N}{N_A}$$ $$m = \frac{171.34\ \mathrm{g/mol} \times 2.41 \times 10^{24}}{6.02 \times 10^{23}\ \mathrm{mol}} = 685.93\ \mathrm{g}$$

Answer:

685.93 g of barium hydroxide
