## How many moles are there in 15 g of SiO2?

For example the average atomic mass of Carbon is 12.011 AMU. The mass of one mole of Carbon is equal to 12.011 grams. The mass of one mole of Lead is equal to 207.2 grams. The mass of one mole of a molecule is equal to the mass of one mole of each of the atoms in the compound.

## How many moles are there in 15.0 grams?

The numeric value of this constant is 6.022×1023. – Now, we can find the number of moles by the formula of moles that is given mass of the substance divided by the molar mass of the substance. – Hence, we can conclude that there are **17.28×1023 moles** in 15 grams of lithium.

## How many moles are in 15g of O2?

So the answer would be (23.584-22.347)grams divided by 16.000 g/mol, or **7.7313×10^-2 moles O2**.

## How many atoms are in 2.50 moles of SiO2?

We are given with 2.5 moles of SO2 , and we need to find the number of atoms in it. We can clearly see from the formula of SO2 that there is **1 silicon atom and 2 oxygen atoms**. Therefore, the total number of atoms in 1 mole of SO2 are 6.022×1023molecules/mole×3atoms/molecule.

## How many grams are in 2.4 moles of Sulphur?

**76.8 grams** of sulphur is required to form 2.4 moles.

## How many molecules are in 0.0125 moles of SiO2?

How many molecules are in 0.0125 moles of SiO2? 0.0 125 molso x **6.024 1023 molecules** Jioz molecular sitamos sioz 13.

## How many moles are in 15 grams of lithium formula?

Answer: There are **2.16 moles** of Lithium in 15 grams. Look at the periodic table to find the molar mass of an element. Molar mass of Lithium is 6.9410 g/mol.

## How many grams are in 0.5 moles of H2SO4?

molar mass of H2SO4 is 98g. given mass or mass present =0.5 × 98 = **49g**.
