0.78 L/min = 780 cm3 / 60 s = 130 cm3/s
0.95 kg/cm3 = 950000 mg/ 1000 mm3 = 950 mg/mm3
(0.78 L/min)(1000 cm^3/1 L)(1 min/60 sec) = 13 cm^3/sec
(0.95 kg/cm^3)(1000 g/kg)(1000 mg/g)(1 cm^3/1000 mm^3) = 950 mg/mm^3.
In each case write the conversion factors in such a way that the units cancel. It’s easy when you do it that way!!
0.307mg*1g/100mg/cm3
=0.00307g/cm3
u convert the mg to g.cancel similar terms.copy the cm3.
2.0.78L-over min*1000cm3/1L*1min/60s
=13cm3/s
convert L to cm3.cm3 is equal to 1 mL. cancel the similar terms.
please check and calculate the answers again.thank you…
