Answer:
Volume of water = 90 ml
Density of water = 0.9982 g/ml
Molar mass of water = 18 g/mole
First we have to calculate the mass of water.
Now we have to calculate the moles of water.
Now we have to calculate the molecules of water.
1 mole of water has molecule of water
4.991 moles of water has molecule of water
Now we have to calculate the number of protons in water.
The number of protons present in 1 molecule of water is,
= 2(1) + 8 = 10 protons
Number of protons present in 1 molecule of water= 10 protons
Number of protons present in molecule of phosphorous = protons
Therefore, the number of protons present in 90 ml of water is protons.
