What volume of a 0.252 M hydroiodic acid solution is required to neutralize 18.0 mL of a 0.151 M barium hydroxide solution

zhenek [66]

Answer: 10.8 M

Explanation:

$M_{A}V_{A}=M_{B}V_{B}\\(0.252)V_{A}=(18.0)(0.151)\\V_{A}=\frac{(18.0)(0.151)}{(0.252)} \approx \boxed{10.8 \text{ M}}$

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.
