The daily value for phosphorus is a 700 mg how many grams of phosphorus are recommended
1 answer:
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!

Answer:
the specific heat of the unknown compound is
Explanation:
Generally the change in temperature of water is evaluated as
Substituting 16.1°C for and 27.4°C for
Generally the change in temperature of unknown compound is evaluated as
Substituting 27.4°C for and 94.3°C for
Since there is an increase in temperature then heat is gained by water and this can be evaluated as
Substituting 179.1 g for m , 4.18 J/g.C for (specific heat of water)
Since there is a decrease in temperature then heat is lost by unknown compound and this can be evaluated as
By conservation of energy law
Heat lost = Heat gained
Substituting 306.9 g for , 8459.6J for
Therefore
