Asolution is prepared by dissolving sugar in water. the solution is 25% by mass, sugar. how many grams of water are in 472 grams of this solution?

352

Explanation:

.75 times 472 because .25 is sugar so .75 is watet

If the sugar makes up 25% of the solution, that means the water makes up 75%, or 3/4, of the solution.

Set up a proportion to solve:

3/4=x/472

Cross multiply:

4×x=472×3

4x=1416

x=354

Therefore, there are 354 grams of water in the solution

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
