The answer is 6 nitrogen atoms.
The given chemical formula is : <u>3Zn(NO₃)₂</u>
Let's find the number of nitrogen atoms by opening the bracket.
Hence, there are 6 nitrogen atoms.
Answer: 2,1,1
Explanation: (2)Na2HPO4=(1)Na4P2O7+(1)H20
There are 0.454 kg in 1 lb
Cross multiply
0.454 kg = 1 lb
X kg. = 50 lb
50* 0.454 = 22.7 kg
Answer : 22.7 kg in 50 lbs
To solve this we use the equation,
M1V1 = M2V2
where M1 is the concentration of the stock
solution, V1 is the volume of the stock solution, M2 is the concentration of
the new solution and V2 is its volume.
1.75 M x V1 = 0.100 M x 2.0 L
V1 = -.11 L
