How many molecules are there in 2 moles of water?
There are approximately 1.204 x 10^24 molecules in 2 moles of water. This is because 1 mole of a substance contains 6.022 x 10^23 molecules. Therefore, 2 moles would contain twice that number.
How many number of moles in 1 litre water?
1 liter of (liquid) water contains 55.5 moles.
How many molecules of sucrose dissolved in 450 g of water are needed to make a 1.3 m solution?
To calculate the number of molecules, first convert 450 g of water to moles (8 moles). With a 1.3 m solution, there are 1.3 moles of sucrose for every 1 liter of water. So, you will need 10.4 moles of sucrose for 8 moles of water. Finally, use Avogadro's number to convert moles to molecules, giving you approximately 6.23 x 10^23 molecules of sucrose.
How many moles is 2 water molecules?
One mole is 6.02 × 1023 molecules. So 2 molecules out of that 6.02 × 1023 would be 2/(6.02 × 1023) or 3.32 ×10-24 moles.
If 5.0 moles of C3H8 react how many molecules of water are formed?
For every mole of C3H8 that reacts, 4 moles of water are formed. Therefore, 5.0 moles of C3H8 will form 5.0 x 4 = 20 moles of water. To convert moles to molecules, you would then multiply by Avogadro's number (6.022 x 10^23 molecules/mol). So, 20 moles of water would equal 20 x 6.022 x 10^23 = 1.2044 x 10^25 molecules of water.
