a chemist dilutes a 1.0 ml sample of 2.0 m kno3 by adding water to it. if the concentration of the solution that is obtained is 0.0080 m, what is its volume? use $m_iv_i = m_fv_f$.\n125 ml\n250 ml\n500 ml\n2,000 ml
Answer
Explanation:
Step1: Identify given values
$M_i = 2.0\ M$, $V_i=1.0\ mL$, $M_f = 0.0080\ M$
Step2: Rearrange dilution formula
$V_f=\frac{M_iV_i}{M_f}$
Step3: Substitute values
$V_f=\frac{2.0\ M\times1.0\ mL}{0.0080\ M}$ $V_f = 250\ mL$
Answer:
250 mL
