The number of molecules that are in balloon are = 2.227 x10^23 molecules
<h3> calculation</h3>
calculate the number of moles of NO
moles = mass/molar mass
molar mass of NO = 14+ 16 = 30 g/mol
moles is therefore= 11.1 g/30g/mol= 0.37 moles
by use of Avogadro's constant that is
1 mole= 6.02 x10^23 molecules
0.37 =? molecules
=(6.02 x10^23 x 0.37 moles)/ 1mole=2.227 x10^23 molecules

Formula for density is mass / volume.
100 ml is volume. 76.5g of cooking oil is
the mass.
Therefore
76.5/100 = .765g/ml
H2O
This equation is a double displacement reaction, and it forms H2CO3, which is very unstable and separates into H2O and CO2.
Answer: 50 grams
Explanation: The water is still only going to be 50 grams. Although it’s in a different state, it didn’t gain or lose any water while being frozen.
