I would like to help if tell me what grade this is.
Answer:
1.2 × 10^22 atoms.
Explanation:
Firstly, cations refers to the positively charged atom in the ionic compound, which is Na+.
Given the mass of NaCl as 1.17g, the number of moles of NaCl can be calculated this:
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mole = mass/molar mass
Mole = 1.17/58.5
Mole = 0.02moles
Using Avagadro's number, 6.022 × 10^23 atoms of Na+ are in 1 mole of NaCl.
In 0.02 moles of NaCl, there are 0.02 × 6.022 × 10^23 of Na+
0.1204 × 10^23 atoms
1.2 × 10^22 atoms of Na+ (cation)
The answer is False. Hope this helps!!!
A B C these are the answers hopes this help <3
First you find moles of HCl.
8.53gHCl(1 mol HCl/36.46gHCl)=0.234mol HCl
Then since molar it is mol/L you divide the number on moles of HCl by the amount of solution in L (0.372L).
Good luck!
