Question

A. 0'45 g/cm³ a kg/l y a mg/ml

B. 28 g/l a kg/ml

C. 450 a dg/ml a g/dal

D. 650 km/s a mm/h

Answer 1

Para realizar este tipo de transformaciones se debe tener todas las magnitudes tabuladas.

A)

$0.45\frac{g}{cm^{3}} =0.45\frac{g}{cm^{3} }* \frac{0.001cm^{3}}{1L}* \frac{1kg}{1000g} =0.00000045\frac{kg}{L}$

$0.00000045\frac{kg}{L} =0.00000045\frac{kg}{L}* \frac{1L}{1000ml}* \frac{1000000mg}{1kg} =0.00045\frac{mg}{ml}$

B)

$28\frac{g}{L} =28\frac{g}{L} *\frac{1kg}{1000g} *\frac{1L}{1000ml} =0.000028\frac{kg}{ml}$

C)

$450\frac{dg}{ml}  =450\frac{dg}{ml} *\frac{0.1g}{1dg}* \frac{10000ml}{1dal} =100\frac{g}{dal}$

D)

$650\frac{km}{s} =650\frac{km}{s} *\frac{1000000mm}{1km}* \frac{1h}{3600s}=180555556 \frac{mm}{h}$
