Answer:
(b) 50 mL = 0.50 L
Explanation:
Metric system is a measurement system that uses decimalized in all their factor, which mean every rank difference can be expressed as a factor of 10(deci=10). The decimalized number makes it easier to convert the unit, make the metric system easier to be learned and used.
The Metric system will use a prefix to determine the factor, a kilo is 1000, mili is 1/1000, centi is 1/100, pico is 1/10^12.
(a) 1 km = 1000 m
True, kilo is 1000
(b) 50 mL = 0.50 L
This option is false. mili is 1/1000, so 50/1000= 0.05 L
(c) 125 mm = 12.5 cm
True, mili is 1/1000 while centi is 1/100.
So 125mm will be: 125mm * 100mm/1000cm= 12.5cm
(d) 23 pm = 0.000 000 000 023 m
True, pico is 10^-12
The answer is b) Water.
a) and c) options are elements and d) option is a mixture.
