Answer:
The mole fraction is the number of moles of something divided by the number of total moles present. First, let us work out the number of moles of KCl present. A 26.3% w/w solution would contain 26.3 g of KCl per 100 g of solution. Hence, 26.3 g of KCl is 26.374.5513 = 0.353 moles
Explanation:
please mark me as brainliest
mass of 1 mole of N is 14g
so mass of 3.45 mole is
3.45 × 14 = 48.3 g
Answer:
The distance between the tank and the upstairs tap is lesser than the distance between the tank and the downstairs tap so water comes out with more force in the downstairs tap than from the upstairs one.

Answer:
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Explanation:
Moles of ,
Moles of acetic acid ,
Mole fraction of water :
Therefore, mole fraction of water in this solution is 0.645 .
Hence, this is the required solution.
