The answer to this question is 2 and 3
3 zots = 7 wots
3 zots × (3 dooms/2 zots) = ⁹/₂ dooms
⁹/₂ dooms × (7 farzes/4 dooms) = ⁶³/₈ farzes
⁶³/₈ farzes × (4 bings/9 farzes) = ⁷/₂ bings
⁷/₂ bings × (2 wots/1 bing) = 7 wots
Answer:
No, assuming that the salt/sugar is already dissolved
Explanation:
As long as the particle size is too big, it won't filter through. Therefore, if it is dissolved, it will pass through the filter.
If you were to throw rocks in there or something, and they are non-dissolvable, then yes.
Answer: The number of N atoms in 137.0 g of N2O3 21.67 x 10∧23 atoms.
Explanation:
- We must obtain the number of moles of the compound: (n = mass/molar mass), mass = 137.0 g and molar mass of N2O3 = 76.01 g/mol.
- n = (137.0 g)/ (76.01 g/mol) = 1.80 mol.
- It is necessary to determine the number of molecules of this sample.
- Every mole contains Avagadro's number (6.02 x 10^23) of molecules.
- The number of molecules = (6.02 x 10^23)(1.80) = 10.84 x 10∧23 molecules.
- Every molecule of N2O3 contain 2 atoms of N.
- The number of N atoms in 137.0 g of N2O3 = (10.84 x 10∧23 molecule) (2 atoms) = 21.67 x 10∧23 atoms.
