## How many moles of atoms are in 32 g of zinc?

**0.50 moles** is your answer.

## How many moles of atoms are in 1.32 g Zn?

Molar mass of Zinc(Zn) = 65.38 g/mol. This means 1 mol of Zn is 65.38g . To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn. Hence, 1.34 g of Zn contains **0.020 moles** of Zinc.

## How many moles are in zinc?

1 grams Zinc is equal to **0.015295197308045 mole**. 1 mole of Zn contains 6.02 × 10²³ Zn atoms. The molar mass of zinc is 65 grams per mole.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## How many moles are in 25 grams of h2so4?

» n= **0.255 mol**

of H₂SO₄ are present in 25 grams of H₂SO₄.

## How many moles of zinc are in 3.30 kg of zinc?

How many moles of zinc are in 3.30 kg of zinc? Express your answer to three significant figures and include the appropriate units. Significant Figures Feedback: Your answer **50.47mol** was either rounded differently or used a different number of significant figures than required for this part.

## How many atoms are in 7 moles of zinc?

1 mole has Avogadro number of atoms, 6.023 x 1023 atoms. Thus, 7 moles of Zn will have 7 x 6.023 x 1023 = **4.216 x 1024 atoms**.
