Ma = 1.66 M

Va = 30.7 mL

Mb = 0.704 M

Vb = 16.7 mL

Using the law <span>of dilution :
</span>
Mf = Ma x Va + Mb x Vb / Va + Vb

Mf = 1.66 x 30.7 +  0.704 x 16.7 / 30.7 + 16.7

Mf = 50.962 + 11.7568 / 47.4

Mf = 62.7188 / 47.4

Mf = 1.323 M

hope this helps!

Can someone convert 150 cm of copper (Cu) wire into mm of Cu wire?​
Vedmedyk [2.9K]

1500 mm of copper wire are produced by converting 150 cm of copper wire.

The following is the centimeter to millimeter conversion factor: 1 cm is equivalent to 10 mm.

Consequently, 150 cm will equal 150 x 10 = 1500 mm.

  • The multi-step process of unit conversion involves multiplying or dividing by a numerical factor.
  • Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
