We can use conversion ratios to convert 0.0850 qts to mL
1 qt = 0.946 L ( This would just have to be something to memorize or if you're lucky, its on a reference chart)
1 L = 1000 ml
If we substitute x for qt ( to make it less confusing- and more like stuff we do in math),
1x = 0.946 L
0.0850x = ?L
Substitute the first equation to the 2nd
0.0850(0.946) = ?L
We need to multiply 0.0850 qt by 0.946 which is 0.08041 L
To convert L to ml, we multiply 0.08041 by 1000, because there are 1000 mL in a L
0.08041*1000 = 80.41 mL
Answer:
0.0850 qt = 80.41 mL
