Sodium hydroxide, NaOH, is a strong base that is sometimes used as a cleaning agent since it can be used to dissolve proteins, grease, oils, and fats. Rank the following in increasing order of their molarity. Rank from lowest to highest. a. 6.625 g NaOH dissolved in 250. mL of water
b. 63.0 g of NaOH dissolved in 1.00 L of water
c. 8.00 g of NaOH dissolved in 500. mL of water
d. 0.0530 of NaOH in 100 mL of water

Rank from lowest to highest - c<a<d<b

Explanation:

Molarity is basically the moles of the solute dissolved in a solvent. Molar mass of NaOH = 39.997 g/mol

a) 6.625 g NaOH dissolved in 250. mL of water

Molarity = 6.625 grams */( 0.250 *39.997) g/mol = 0.66

b) 63.0 g of NaOH dissolved in 1.00 L of water

Molarity = 63 grams */( 1 *39.997) g/mol = 1.575

c) 8.00 g of NaOH dissolved in 500. mL of water

Molarity = 8 grams */( 0.5 *39.997) g/mol = 0.331

d) 0.0530 of NaOH in 100 mL of water = 0.53

Rank from lowest to highest - c<a<d<b

i think it is d. e because the next one is igneous.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
