Question

Given 2.3 grams of zinc how many moles is present

Answer 1

Answer: Moles of Zinc for the given amount is 0.0351 moles.

Explanation:

We are given 2.3 grams of zinc and we need to find the moles of it. To calculate the moles, we use the following equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Mass of Zinc given = 2.3 grams

Molar mass of Zinc = 65.39g/mol

Putting values in above equation, we get:

$\text{Moles of Zinc}=\frac{2.3g}{65.39g/mol}\\\\\text{Moles of Zinc}=0.0351mol$

Hence, moles of Zinc for the given amount is 0.0351 moles.

Answer 2

Divide by its molar mass
