a. Calculate the number of molecules in 5 moles of water.

One mole is the amount of substance that contains as many elementary particles as 12 g of _^12C isotope of carbon. Calculate the number of moles in 1 litre of water ("Density of water is "lg//mL) . Also calculate the number of water molecules in 1 litre of water

One mole is the amount of substance that contains as many elementary particles as 12g of C^12 isotope of carbon. Calculate the number of moles in 1 litre of water(Density of water is 1g/mL). Also calculate the number of water molecules in 1 litre of water.

Calculate the number of molecules present in 1 g of water.

Calculate the number of molecules in (i) 1 g of water and (ii) 5600 cm^3 of nitrogen at STP.

A person suffering from urolithiasis is advised by a doctor to take 20 glasses of water daily. Assuming one glass of water contains 180 ml, calculate the number of moles and molecules of water consumed daily by the patient. (Hint: density of water = 1 g//ml)

Calculate the number of molecules In 90g of water. (Hint -Atomic mass H=1, 0=16)

Calculate the number of molecules in 11.2 litres of SO_(2) gas at NTP.

Calculate the number of molecules in each of the following: 1 g N_2

Find the number of moles in 45g of water.
