Answer :
The amount of blood in 1L is 150g
we know that
1 litre = 1000mL
according to unit conversion factor or factor label method
[tex]\frac{1000mL}{1L}=1=\frac{1L}{1000mL}[/tex]
thus the amount of hemoglobin in 1mL will be
[tex]hemoglobin=\frac{150}{1000}=0.15g[/tex]
Thus amount of hemoglobin in 10mL will be
[tex]=0.15x10=1.5g[/tex]
The hemoglobin in 10mL = 1.5g
