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 :)
We can use the ideal gas law equation to find the volume of the balloon.
PV = nRT
where
P - pressure - 0.992 atm x 101 325 Pa/atm = 100 514 Pa
V - volume
n - number of moles - 8.80 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature in kelvin - 25 °C + 273 = 298 K
Substituting these values in the equation
100 514 Pa x V = 8.80 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
V = 217 L
volume of balloon is 217 L
A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The subscripts also indicate the ratios of the elements.
it can hold 5 orbitals in the 4d sunshell and there 5 in the orbital i believe that a maxama of ten electrons allowed if im wrong then im sorry
1. Sodium hydrogen carbonate
2.Barium Chloride
3.Lithium Fluoride
4.Aluminum hydroxide
5.Strontium iodide
