How many moles are in 9 grams of H2O?
Water has 18 grams per mole so 9 grams is 0.5 moles of water.
How many molecules are in 9g of water?
3.01 × 10. 6.022 × 10.
How many moles are in 10g of water?
1 mole of water weighs 18g. 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 moles of oxygen are in 9g of water?
The second step is calculate the number of moles of water in 9gWe need to use the equation moles=mass/Mr 2H2 + O2 -> 2H2OMass ? 9gMr 32 18 Moles 9/18=0.53. We can now work out the number of moles of oxygen needed to make 0.5 moles of water.
Which one has more molecules 9g of water and 9g of sugar?
Answer: 9 g of water has more molecules. According to avogadro’s law, 1 mole of every substance weighs equal to molecular mass and contains avogadro’s number of particles.
How many molecules of water are there in 1g of water?
Answers (1)
or 1 g of water contains (6.022 x 1023)/ 18 water molecules and the number comes out to be 3.3455 x 1022. So the number of water molecules present in 1 g of water is 3.3455 x 1022.
How many moles is 17g of water?
Hence 17 gm of H2O2 = 1/ 34 ×17 = 1/ 2 = 0.5moles.
What is the number of molecules in 9g of steam?
9 gram of steam contain 3.015*10^23 H2O 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 H2O molecules are in 10 grams of water?
10 g of H2O cotains =6.022×102318×10 = 3.34×1023 molecules.
