How many molecules of water are there in 25 g?
Here we have 25.0 g/(18.0g/mole) = 1.39 moles water (3 sig figs). Multiply 1.39 moles times the definition of a mole to arrive at the actual number of water molecules: 1.39 (moles water) * 6.02 x 1023 molecules water/(mole water) = 8.36 x 1023 molecules water.
What is the total number of molecules of water in 0.25 mole of water?
How many water molecules are in 4.0 moles of H2O?
If you have 6.022⋅1023 molecules of water, then you can say for a fact that you have 1 mole of water. Now, you know that your sample contains 4.0 moles of water. In order to find the number of molecules of water it contains, you can use Avogadro’s constant as a conversion factor.
What is the mole of 20 gram 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 h20 are in 0.25 mole?
4.5 g of are present in 0.25 mole of it.
How many molecules are in 0.25 moles?
so, 0.25 moles of oxygen there is 6.023/4×10^23 molecules.
How many molecules of water are present in half mole of water?
Answer: A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water.
