The amount of grams of phosphorus that are recommended is 0.700 g
Why?
This is an unit conversion problem. To convert between units we use conversion factors. In this case the conversion factor we want is from mg to g, and this is relatively simple: 1000 mg = 1 g. Now, we arrange the quantities in the following way:
Conversion factors are really useful for converting units! Just remember to put the unit you don't want at the bottom, and the one you want at the top.
Have a nice day!

The chemical formula of butane is C4H10.
This is a simple algebraic problem, specifically for the mixture type of problem. Let x be the mass of 40% solution and y be the mass of 70% solution. The first equation would then be:
x + y = 20 --> eqn 1
The second equation would be the mass balance shown below:
(x)(0.40) + y(0.70) = 20(0.52) --> eqn 2
Rearranging eqn 1,
x = 20 - y
Substitute this to eqn 2:
(20 - y)(0.40) + y(0.70) = 20(0.52)
Solve for y,
y = 8 grams
Finally, solve for x.
x = 20 - 8 = 12 grams
<em>Therefore, Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.</em>
The kinetic energy will increase. the molecules in a gas will move freely so it moves crazy like 10,000 cheetah on a run going in different directions
