The new concentration of sodium phosphate is 0.315 mol·L⁻¹.
We can use the dilution formula
:
<em>c</em>₁<em>V</em>₁ = <em>c</em>₂<em>V</em>₂
We can rearrange the formula to get
<em>c</em>₂= <em>c</em>₁ × (<em>V</em>₁/<em>V</em>₂)
∴ <em>c</em>₂ = 1.50 mol·L⁻¹ × (21.00 mL)/(100.0 mL)] = 1.50 mol·L⁻¹ × 0.2100
= 0.315 mol·L⁻¹
