72.2 moles of water is spilled

Explanation:

as moles=mass/mr

so mr of water is 16+2=18

13000/18=72.2

for the second one you can work out the moles of o2

by using moles= number of particles /6.02*10^23

so 4.65*10^26/6.02*10^23

so i got 772.4 on my calculator  to work out the amount of mass

u use the equation mass=moles*mr

so 777.2*16=12435g of oxygen gas

ask someone else I will help later
