Answer:
0.311 mmol/L
Explanation:
109 μmol = 109*10^(-6) mol
109*10^(-6) mol = 109*10^(-6) mol*(10^3 mmol/1mol) = 109*10^(-3) mmol =
=0.109 mmol
350 mL = 0.350 L
0.109 mmol/0.350 L = 0.311 mmol/L
For cm to m, you need to divide by 100 to get m:
26cm/100= 0.26m
For hr to min, you need to multiply by 60 to get min:
4hr x 60= 240min
For km to m, you need to multiply by 1000 to get m:
3.25km x 1000= 3250m
For ft to in, you need to multiply by 12 to get in:
5ft x 12=60in
So we have:
0.26m
240min
3250m
60in
