Question

The weight of KOH in its 50 milliequivalent is 1. 1.6 2. 2.2 3. 2.8 4. 4.8

Answer 1

50 Mili equivalents = 50 x 10-3 equivalents
Wt. of 1 equivalent.KOH = 56 g/eq (same as molar wt. of KOH)
So, wt. of 50 x 10 equivalents = 50 x 10'equivalent x 56 g/equivalent = 2.8 g

Answer 2

The weight of KOH in 50 mill equivalent is 3. 2.8 g

Explanation:

Molar mass of KOH = 56 g

Molar mass = weight of one equivalent of KOH

From the given,

$\text{ 50 milliequivalents } = 50 \times 10^{-3} \ \text{equivalents}$

For  one equivalent weight of KOH = 56 g/mol

Hence,

$50 \times 10^{-3} \text { equivalents }=50 \times 10^{-3} \times 56$

$=2800 \ g \times 10^{-3}$

$\text { Weight } =2.8 \ g$

Therefore, the weight of KOH in its 50 milliequivalent is 2.8 g
