Question

Determine the number of representative particles in each of the following:

Answer 1

Answer:

(a) 0.294 mol silver = $1.770 * 10^{23}$  

(b) 8.98 * 10-3 mol sodium chloride - $5.407 *10^{23}$  

(c) 23.3 mol carbon dioxide  = $1.403 * 10^{25}$

(d) 0.310 mol nitrogen (N2) = $1.866 * 10^{23}$

Explanation:

In one mole there are $6.022 * 10^{23}$ atoms/molecules

(a) 0.294 mol silver = $6.022 * 10^{23} * 0.294 = 1.770 * 10^{23}$  

(b) 8.98 * 10-3 mol sodium chloride - $5.407 *10^{23}$  

(c) 23.3 mol carbon dioxide  = $23.3 * 6.022 * 10^{23} = 1.403 * 10^{25}$

(d) 0.310 mol nitrogen (N2) = $0.310 * 6.022 * 10^{23} = 1.866 * 10^{23}$
