how many atoms of each element are in 4na₃po₄?\n3 sodium, 1 phosphorus, 4 oxygen\n4 sodium, 4 phosphorus, 4…

Explanation:

Step1: Analyze sodium atoms

The formula is $4Na_3PO_4$. For sodium ($Na$), the sub - script is 3 and the coefficient is 4. So the number of sodium atoms is $4\times3 = 12$.

Step2: Analyze phosphorus atoms

For phosphorus ($P$), the sub - script is 1 and the coefficient is 4. So the number of phosphorus atoms is $4\times1=4$.

Step3: Analyze oxygen atoms

For oxygen ($O$), the sub - script is 4 and the coefficient is 4. So the number of oxygen atoms is $4\times4 = 16$.

Answer:

D. 12 sodium, 4 phosphorus, 16 oxygen
