You can view more details on each measurement unit: molecular weight of Pb or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Pb, or 207.2 grams.

## How many grams are in a mole of lead?

One mole of lead (Pb) contains 6.02 × 1023 atoms and its mass is 207.2 g.

## How many grams are in each mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many moles are in 0.8 g of PB?

To convert from grams to moles, use the atomic weight of Pb (207.2 g/mol). Hint: Assuming the sample is 100% Pb, the result is: (0.8 g Pb / 207.2 g mol^{–}^{1} Pb) = 0.003861 moles Pb.

## How many grams are in 1 mole of uranium?

Explanation: Alternatively, we could work out the molar quantity, knowing that Avogadro’s number , NA uranium atoms have a mass of 238.03⋅g . We thus speak of the molar mass of uranium as 238.03⋅g⋅mol−1 . And thus moles of uranium=1000⋅g238.03⋅g⋅mol−1=4.20⋅mol .

## What is the mass of Pb?

36.5 gm.

## What is mole in chemistry?

A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## How many grams are in 1 mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How many moles are in 10 g of PB?

2.5mols of helium is present in 10g of helium.

## How many moles are in PB?

Unit mole of every element consist of 6.022×1023 6.022 × 10 23 atoms. In other word, 6.022×1023 6.022 × 10 23 atoms are present in 1 mole of Pb. Therefore, 1 atom will be present in 16.022×1023 1 6.022 × 10 23 moles of Pb.

## How many moles are in 17.4 g of lead?

The moles present in 17.4 g of lead are 0.0840 moles.

## How many moles are in 119 g uranium?

119 grams = 0.49993908305290474 Moles of Uranium

Please enter another number of grams of uranium that you want converted to moles of uranium.

## How many grams is a platinum atom?

The mass of 4×1021 atoms Pt is ≈ 1 g Pt.

## How many atoms are in 1 kg of uranium?

The atomic mass of U-238 is 238.05 grams, so the number of atoms, N, in 1 kg is Avogadro’s number times 1000g/238, or atoms.
