Question

q2: what volume, in ml, of 4.0 h₂so₄ is diluted to make 250.0 ml of a 0.15 m h₂so₄?

Explanation:

Step1: Use dilution formula

$M_1V_1 = M_2V_2$

Step2: Identify given values

$M_1 = 4.0\ M$, $M_2=0.15\ M$, $V_2 = 250.0\ mL$

Step3: Solve for $V_1$

$V_1=\frac{M_2V_2}{M_1}=\frac{0.15\ M\times250.0\ mL}{4.0\ M}$
$V_1 = 9.375\ mL$

Answer:

$9.375\ mL$
