# Frequent question: How many grams are in a mole of lead?

Contents

One mole of a substance is equivalent to one molar mass of that substance. One mole of lead is equivalent to 207.2g of lead.

## How do you convert grams to mole?

Divide the number of grams of the compound, NaOH, by the molecular weight and as a result, the grams (g) unit cancels and all we have left is the unit mol (moles).

## How many grams are in an atom of lead?

Explanation: You know that the mass of an individual lead atom is equal to 3.4⋅10−22 grams. A substance’s density tells you what its mass per unit of volume is. In this case, you know that lead has a density of 11.3 g/cm3 , which means that each cm3 of lead will have a mass of 11.3 g .

## What is 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.

## Why do we convert moles to grams?

In chemistry, the mole is the standard measurement of amount. When substances react, they do so in simple ratios of moles. … So the problem is that, when we compare amounts of one substance to another using moles, we must convert from grams, since this is the information we get from balances.
