V = 500ml = 0,5 l
c = 0,75 M

c = n/V
n = c × V
n = 0,75 × 0,5 = 0,375[mol]

M NaCl = 58,5 g/mol

1 mol ------- 58,5 g
0,375 mol ----- x g

x = 0,375 mol × 58,5 g / 1 mol = 21,94 g

Answer: In this solution there are 21,94 g of sodium chloride.

A compound containing Na, C, and O is found to have 1.06 mol Na, 0.528 mol C, and 1.59 mol O. What is the empirical formula of t
Effectus [21]

Given :

Moles of Na : 1.06

Moles of C : 0.528

Moles of O : 1.59

To Find :

The empirical formula of the compound.

Solution :

Dividing moles of each atom with the smallest one i.e 0.528 .

So,

Na : 1.06/0.528 = 2.007 ≈ 2

C : 0.528/0.528 = 1

O : 1.59/0.528 = 3.011 ≈ 3

Rounding all them to nearest integer, we will get the number of each atom in the empirical formula.

So, empirical formula is Na_2CO_3 .

Hence, this is the required solution.
