## How many moles are in 10g?

10/18 moles = 10/18 * 6 * 10^23 number of molecules = 3.33 * 10^23 molecules of water. Each molecule of water has 3 atoms, so the total number of atoms in 10g of water is 3*3.33*10^23 = **10^24**.

## How many molecules are there in 10g of hydrogen?

**022×10^23 mol**^-1 =no. of hydrogen atoms.

## How many moles are in one gram of hydrogen?

Because the molecular mass of Hydrogen is 1 gram/mole, there is **1 mole** of hydrogen in 1 gram of hydrogen atoms. For every mole, there are 6.02*10^{23} atoms, so in 1 gram of hydrogen there are 6.02*10^{23} hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.

## How many moles is 8g of hydrogen?

Answer Expert Verified

= 3.01 x 10²³ moles. Therefore, 8 g of H₂ will have = 8 x 3.01 x 10²³ moles = **24.08 x 10²³ moles**. Thus, 8 g of H₂ will have 24.08 x 10²³ moles of hydrogen molecules.

## How many moles are present in 10 g of H2O?

**One mole** of any substance weighs about the same as the molecular mass of that substance. Hence, there are [3.34times {10^{23}}] molecules of [{H_2}O] present in a 10 gram sample of [{H_2}O] .

## How many grams is 10 moles of water?

Number of moles=Mass/Molecular Mass. n=m/M. 10=m/18. Therefore,Mass of 10 moles of water =10×18=**180 g**.

## How many atoms are present in 10g of he?

**2.5m**ols of helium is present in 10g of helium.

## Which contains the greater number of particles 10.0 g of water H2O or 10.0 g of mercury Hg )?

**Mercury**: the relative atomic mass of mercury is 201 3 Page 4 Therefore 10.0 g is equivalent to (10 g/201 g mol–1) mol of mercury (≈ 0.05 mol) 10.0 g of water contains more particles than 10.0 g of mercury.

## How many moles are present in 20 grams of water?

so mole of water weighs 18g. which implies 18g of water =1mole. if 18g,=1mole then 20g =20/18. therefore 20g=**1.11111**.

## How many grams of hydrogen are present in 3 moles of hydrogen?

Therefore **6.00 grams** of hydrogen gas is being used.
