Answer:
B)
Explanation:
Mutations are changing in chromosomes.
The 3 outside means to multiply the inside by that number. AL(NO2)3 has
1 N inside
1 x 3 = 3 nitrogen atoms
The molar mass of Al(NO3)3= 212.996 g/mol
nitrogen is 14 g/mol and is 19.7% if the molar mass
19.7% of 12 g = 2.354g
2.354/14 = 0.196 N
Answer:
0.0423 L
Explanation:
Molarity can be represented by the following ratio:
Molarity = moles / volume (L)
You can plug the given values into the equation and simplify to find the volume.
Molarity = moles / volume
0.730 M = 0.0309 moles / volume
(0.730 M) x volume = 0.0309 moles
volume = 0.0423 L
