4.8 g/cm3 with sig figs since it's mass/volume you divide 76 grams by 16 cm3
Usually when scientist wants to test whether one compound or one phenotype is related to another phenotype. Then they need to control this variable when conducting experiments.
Around 2,400 seconds would be in a 40.0 minute class
Answer:
0.5667 M ≅ 0.57 M.
Explanation:
- It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
<em>(MV) before dilution = (MV) after dilution.</em>
M before dilution = 1.5 M, V before dilution = 340 mL.
M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.
∴<em> M after dilution = (MV) before dilution/(V) after dilution</em> = (1.5 M)(340 mL)/(900 mL) = <em>0.5667 M ≅ 0.57 M.</em>
Answer:
<u>NO</u>
Explanation:
To maintain electric neutrality, the atom has to have equal number of electrons and protons. Therefore, it needs to have 6 electrons to be neutral.
