Answer:
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
hope it helps :)
