Interesting enough, a recent study in 2009, at the University of Chicago indicated that many different kinds of moles contain a family of virus that can spread by way of physical contact. Replication of the virus and the resulting moles often develop in the new host subjects. The worst of the problem is that these types of moles often create virulent cancerous cells that metastasize very quickly. Now, can we deduce that sharing razors causes moles? Maybe. Even worse, it may be that sharing razors causes cancer.
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
this is a easy one. There are only 0.04166 moles.
The mole ratio to convert from moles of a to moles of b is determined by the coefficients of a and b in the balanced chemical equation. For example, if the balanced equation is 2A + 3B -> 4C, the mole ratio would be 3 moles of B for every 2 moles of A.
2 moles of Ca and 4 moles of OH
From the balanced equation, 2 moles of A3 react with 3 moles of B2 to produce 6 moles of AB. Therefore, if 10 moles of A3 are reacted, the ratio of moles of AB produced would be (10 moles A3 / 2 moles A3) * 6 moles AB = 30 moles AB.
If it is 5 molar: 5 moles per liter, then you start with 5 moles of salt. You will always have 5 moles of salt, but it is spread among a bigger volume. So you want it to be 2 moles per liter, so the amount of salt is 2*V, but we know that there are 5 moles, so we have 2*V = 5, and V = 5/2 = 2.5 Liters. Since we started with 1 liter, we must add 1.5 liters.
Of course 6 moles.
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
For every 2 moles of A3, 3 moles of B2 react to form 6 moles of AB. Since we have 10 moles of A3, we need to double the moles of B2 reacting, which would be 15 moles of B2 to fully react with the 10 moles of A3. This would produce 30 moles of AB.
