Answer : The correct option is "record 10.00 ml in the notebook after using it."
Explanation :
If an instrument has "10 mL TD" written on it, that means the instrument is meant To Deliver (TD) 10 mL of volume.
Therefore the option that has 5.00 mL is not correct.
"+/- 0.01 mL" indicates the precision of the instrument. We know that no measurement is 100% accurate and there is always some uncertainty associated with any measurement.
Here, 0.01 indicates the uncertainty in the measurement.
When we have 0.01 mL , that means the instrument can record precisely to the hundredths place.
The more the significant figures, the greater is the accuracy of the measurement.
Therefore when we use an instrument that has "+/- 0.01 mL" written on it, we should record the reading as 10.00 mL
Answer:
The answer to your question is: 6 grams of hydrogen
Explanation:
Data
3.0 moles of hydrogen
1.5 moles of oxygen
3 moles of water
# of grams of hydrogen required to form 3 moles of water?
Equation
H₂ + 1/2 O₂ ⇒ H₂O
3 mole 1.5 moles 3 moles
Atomic weight of H₂ = 2 g
1 mole ----------------------- 2 g
3 moles --------------------- x
x = 3(2)/1 = 6 grams of hydrogens
Answer:
