Calculate the no. Off molecules atom in 360gm of water...??
To calculate the number of molecules in 360g of water, you need to use the concept of moles and Avogadro's number.
1. First, determine the molar mass of water. The molecular formula of water (H2O) consists of two hydrogen atoms (with a molar mass of approximately 1.008 g/mol) and one oxygen atom (with a molar mass of approximately 16.00 g/mol). Adding these together, we have:
Molar mass of water = (2 x 1.008 g/mol) + 16.00 g/mol = 18.016 g/mol
2. Next, use the molar mass of water to find the number of moles. Divide the given mass (360g) by the molar mass of water:
Number of moles = Mass / Molar mass = 360g / 18.016 g/mol
3. Calculate the Avogadro's number, which represents the number of molecules in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23 molecules/mol.
Avogadro's number = 6.022 x 10^23 molecules/mol
4. Finally, multiply the number of moles by Avogadro's number to find the number of molecules:
Number of molecules = Number of moles x Avogadro's number
So, to calculate the number of molecules in 360g of water, plug in the values:
Number of molecules = (360g / 18.016 g/mol) x (6.022 x 10^23 molecules/mol)
By performing this calculation, you will obtain the accurate number of molecules in 360g of water.
