7. convert 5.2 cm of magnesium (mg) ribbon to mm of mg ribbon.

52 mm

We are given;

Required to convert it to cm

We are going to use the appropriate conversion factor;

Kilometer(km)

10

Hectometer (Hm)

10

Decameter (dkm)

10

Meter(m)

10

Decimeter (dm)

10

Centimeter (cm)

10

Millimeter (mm)

Therefore; the appropriate conversion factor is 10mm/cm

Thus;

5.2 cm will be equivalent to;

= 5.2 cm × 10 mm/cm

= 52 mm

Therefore, the length of magnesium ribbon is 52 mm

idk what the question is about
