There are 1000mL per 1 L.
Mathematically.
1000mL
1L
If there are 1000mL in 1 L, then 1 mL is 1000th of a L.
Using dimensional analysis.
1 mL * 1 L = 0.001 L = 1 (10-3) L = 1 mL
1000 mL
So, 425.6789 mL =
425.6789 mL * 1 L =.4256789 L
1000 mL
If there is 1 g in 1 mL, and 1000 mL in 1 L, then there are 1000g in a L, correct?
In this question you do not have 1g in 1 mL though.
