Step 1: Define

4 mol Na₃P

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

= 2.4088 × 10²⁴ atoms Na₃P

Step 4: Check

We are given 1 sig fig. Follow sig fig rules and round.

2.4088 × 10²⁴ atoms Na₃P ≈ 2 × 10²⁴ atoms Na₃P

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
