how many atoms of nitrogen are in the chemical formula ni(no3)2?\no 2\no 1\no 6\no 3
how many atoms of nitrogen are in the chemical formula ni(no3)2?\no 2\no 1\no 6\no 3
Answer
Explanation:
Step1: Analyze the sub - formula
In the formula $Ni(NO_3)_2$, the sub - formula inside the parentheses is $NO_3$.
Step2: Consider the outer coefficient
The outer coefficient 2 multiplies everything inside the parentheses. Since there is 1 nitrogen atom in $NO_3$, when multiplied by 2, the number of nitrogen atoms is $1\times2 = 2$.
