What mass of li3po4 is needed to prepare 500 ml of a solution having a lithium ion concentration of 0.175 m?

Explanation:

The first step is to find the moles of  , using the equation:

Where,

Plug in the values into the equation:

Solving for mole:

Now, the have to write the chemical equation to find the molar ratio between and , so:

The molar ratio then is 1:3, using this molar ratio we can convert from moles of to moles of , so:

Finally, we have to conver from moles of to grams of   using the molar mass of (115.79 g/mol), so:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
