An aqueous solution of sodium hydroxide contains 20% naoh by mass. it is desired to produce an 8% naoh solution by diluting a stream of the 20% solution with a stream of pure water.(a) calculate the ratios (g h2o/g feed solution) and (g product solution/g feed ) determine the feed rates of 20% solution and diluting water needed to produce 2310 lb/min of the 8% solution.

Find the number of moles of argon in 364g of argon.

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid

what is your question? collegechemistry 5+3 pts in november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
