Answer:

0.2098mole

Explanation:

we know ,

1 mole (gas) =22.4 liters [in STP]

so,

22.4 liters  argon gas = 1 mole

4.7 liters  argon gas = (4.7/22.4)mole

                                  =0.2098mole

Convert .0150 km to meters and express the correct significant figures

<h3>Answer:</h3>

15.0 meters

<h3>Explanation:</h3>
  • Kilometers are units used to measure length.
  • Length is also measured using other units which include meters, centimeters, decimeter, millimeter, etc
  • To convert one unit to another we use conversion factors.

In this case to know inter-conversion between units of measuring length, we consider the following;

Kilometer(km)

10

Hectometer(Hm)

10

Decameter(dam)

10

Meter (M)

10

Decimeter (dm)

10

Centimeter (cm)

10

Millimeter (mm)

Therefore, to convert km to meter we use the conversion factor (10×10×10) 1000 m/km.

Thus;

0.0150 km is equivalent to;

= 0.0150 km × 1000 m/Km

= 15.0 meters

Thus, 0.0150 km is equivalent to 15.0 meters.
