Question

How many milliliters of a 6.00M NaCl solution are needed to make 250.0 milliliters of a 0.500M NaCl solution

Answer 1

Answer:20.83mL

Explanation:Given:C1=6.00C1​=6.00MC2=0.500C2​=0.500MV2=250.0V2​=250.0mL =0.250=0.250LPlugging in the values:6.00 M×V1=0.500 M×0.250 L6.00M×V1​=0.500M×0.250LSolving for V1V1​:V1=0.500 M×0.250 L6.00 MV1​=6.00M0.500M×0.250L​V1≈0.02083 L×1000 mL1 L≈20.83 mLV1​≈0.02083L×1L1000mL​≈20.83mL
