Answer:
328 ml
Explanation:
We have given final volume =575.2 ml=0.575 L
Final concentration = 0.8012 M
We know that moles of copper(II) nitrate = final volume ×final concentration =0.8012×.0575=0.4606 moles
We have to find initial volume
So initial volume 
Answer is: <span>the predicted </span>density for calcium is 1.61 g/cm³.
d(Sr) = 2.63 g/cm³; density for strontium.
d(Ba) = 3.65 g/cm³; density for barium.
Ar(Sr) = 87.62 atomic weight for strontium.
Ar(Ba) = 137.33; atomic weight for barium.
Ar(Ca) = 40.08; atomic weight for calcium.
d(Ba) - d(Sr) = 3.65 g/cm³ - 2.63 g/cm³.
d(Ba) - d(Sr) = 1.02 g/cm³.
d(Ca) = d(Sr) - 1.02 g/cm³.
d(Ca) = 2.63 g/cm³ - 1.02 g/cm³.
d(Ca) = 1.61 g/cm³.

Answer:
We know that the mass of 1 mol of hydrogen is 1 gram. 1 mol of hydrogen is 6.022⋅1023 atoms. To find the mass of 1 atom, we just have to divide
