can i get brainliest? lol :) hope that helps
3. a) 320 mL x 1 L/1000 mL = 0.320 L
b) 948 mL x 1 L/1000 mL = 0.948 L
c) 1834 mL x 1 L/1000 mL = 1.834 L
d) 3267 mL x 1 L/1000 mL = 3.267 L
4. a) 0.75 L x 1000 mL/1 L = 750 mL
b) 0.28 L x 1000 mL/1 L = 280 mL
c) 1.32 L x 1000 mL/1 L = 1320 mL

Answer:
Pupil is the blackness in the middle, which is technically a "hole" in your eye which light goes through. The iris is the part that has color.
Explanation:
When someone asks you "what color are your eyes," they really mean "what color are your irises"
Answer:
0.257M HNO3
Explanation:
The reaction of HNO3 with Ba(OH)2 is:
2 HNO₃ + Ba(OH)₂ → 2 H₂O + Ba(NO₃)₂
That means 2 moles of HNO3 reacts with 1 mole of Ba(OH)2.
51,3mL of 0.250M Ba(OH)2 are:
0.0513L ₓ (0.250mol / L) = 0.0128moles
Moles of HNO3 are:
0.0128moles Ba(OH)2 ₓ (2 mol HNO3 / 1 mol Ba(OH)2) = 0.0257mol HNO3
As these moles are in 0.100L:
0.0257mol HNO3 / 0.100L = <em>0.257M HNO3</em>

I hope it helps!
Don't know sorry the answer.
