Answer: 0.25mol
Explanation: RMM of compound = (3 x 1) + (30) + (16 x 4) = 97g
# of moles = 25g / 97g = 0.25mol
Answer:
3.42×10²¹ of particles
Explanation:
To determine the number of particles we should know, that:
1 mol of anything contains 6.02×10²³ particles
Therefore we have to find out, how many moles corresponds to 0.332 g of NaCl.
The conversion is: 0.332 g / 58.44 g/mol = 0.00568 moles
The rule of three to determine the number of particles is:
1 mol of NaCl has 6.02×10²³ particles
0.00568 moles must have (0.00568 . 6.02×10²³ particles )/1 = 3.42×10²¹
Answer:
The answer is c
Explanation:
Because all of the Other ones did not make sense
When that happens, you get a plasma — the fourth state of matter.
