Milliequivalent is a unit that made from millimol unit multiplied by the valence of the atoms. Calcium has 2 valence electron so the mEq would be twice as much as the mol. The solution has 155meq/liter and the volume is 1850ml. Then, the amount of calcium in the solution should be:

1850ml * (155mEq/1000ml) / (2mEq/mmol)= 143.375mmol= 0.144 mol

How could an alpha particle pass straight through the metal foil and strike the center of the phosphor screen on the other side
djverab [1.8K]
I think you refer to  Rutherford's Gold Foil Experiment alpha particles pass through because of the enormous amount of empty space inside the atom. 


>>>more details here<<<
to have its trajectory affected the alpha particle has to pass "near" the nucleus to interact with the positive charge of the nucleus.
the fact is that internally the gold atoms are basically empty space and the nucleus represents only a small portion of the entire volume. only few alpha particles pass near the nucleus

How many grams are in 3.67 moles of lithium cyanide
OLga [1]

Answer: 120.9 grams

Explanation:

Given the question : How many grams are in 3.67 moles of Lithium cyanide?

Chemical formula of lithium cyanide = LiCN

Molar mass of LiCN: Li = 6.941 ; C = 12, N = 14

LiCN = (6.941 + 12 + 14). = 32.941 g/mol

(Gram of substance / mole of substance) = (molar mass of substance / one mole)

(Gram of substance / 3.67) = (32.941 / 1)

= gram * 1 = 3.67 * 32.941

Gram of substance = 120.89347

= 120.9 grams

If you have 3 moles of FeCl3, how many moles of MgCl2 can be produced? FeCl3 + Mg --&gt; MgCl2 + Fe
oksian1 [2.3K]

Answer: 154.09 g

Explanation:

3 Mg + 2 FeCl3 = 3 MgCl2 + 2 Fe

The mass of MgCl2 produced is calculated:

m MgCl2 = 175 g FeCl3 * (1 mol FeCl3 / 162.2 g) * (3 mol MgCl2 / 2 mol FeCl3) * (95.21 g MgCl2 / 1 mol) = 154.09 g
