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

15.0 meters

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.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
