<em>Hello, </em>
<h3><u>QUESTION)</u></h3>
During telophase, the cell, each pole of which inherits the same number of single chromosomes, begins to divide into 2: this is cytodieresis.
Answer:
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
Explanation:
Answer:
= 6.7 × 10^-6 M
Explanation:
The number of moles of AgCl
= 0.0012 g/143.32 g/mol
= 8.373 × 10^-6 Moles
Concentration or Molarity = moles × volume
800 grams = 800 cm³ = 0.8 L
= 8.373 × 10^-6 Moles × 0.8 L
= 6.7 × 10^-6 M
Answer is: dissolve 74,9 grams CuSO₄·5H₂O in one liter volumetric flask.
V(CuSO₄·5H₂O) = 1 L.
c(CuSO₄·5H₂O) = 0,30 mol/L.
n(CuSO₄·5H₂O) = V(CuSO₄·5H₂O) · c(CuSO₄·5H₂O) .
n(CuSO₄·5H₂O) = 1 L · 0,3 mol/L.
n(CuSO₄·5H₂O) = 0,3 mol.
m(CuSO₄·5H₂O) = n(CuSO₄·5H₂O) · M(CuSO₄·5H₂O).
m(CuSO₄·5H₂O) = 0,3 mol · 249,7 g/mol.
m(CuSO₄·5H₂O) = 74,9 g.
Cooks should use sea salt in recipes instead of regular table salt.
