Mercator and conic projections are different because conic projections have a cone/triangle shape and Mercator projections have a cylindrical look to them. They are both the same because they show the world. However, the world is viewed from very different perspectives. For example, a Mercator projection is from the point of view of a bird and the conic is from a view from space.
Sr N(e⁻)=38
Sr²⁺ N(e⁻)=38-2=36
36e⁻
I believe it is less dense.. that is why ice floats on water
Answer:
0.156mol
Explanation:
Number of moles of a substance can be calculated from its mass by dividing its mass by molar mass i.e.
Number of moles (n) = mass/molar mass
Molar mass of PbCl4 is as follows, where Pb = 207.2g/mol, Cl = 35.5g/lol
PbCl4 = 207.2 + 35.5(4)
= 207.2 + 142
= 349.2g/mol
Using: mole = mass/molar mass
mole = 54.32 grams ÷ 349.2g/mol
mole = 0.1555
mole = 0.156mol
