Question 894220
Probably what is expected is
{{{(50Liters/"1 minute")(1minute/"60 seconds")(1000mL/"1 Liter")=50*1*1000/(1*60*1)}}}{{{mL/second}}}
or
{{{(50Liters/"1 minute")(1000mL/"1 Liter")(1minute/"60 seconds")=50*1*1000/(1*60*1)}}}{{{mL/second}}}
Each of the factors after {{{(50Liters/"1 minute")}}} is equal to {{{1}}} so multiplying times those factors does not change the quantity.
You could also think of it as
50 L = 50,000 mL ,
and
1 minute = 60 seconds , so
{{{50Liters/"1 minute"=50000mL/"60 seconds"= 50000/60}}}{{{mL/s=833}}}{{{mL/s}}}
