What is the volume of liquid in the granulated cylinder shown below? Be sure to read the bottom of the meniscus and estimate the volume to one decimal place beyond the accuracy of the cylinder.

1.95 gallons [liquid].

Explanation: To convert any value in quarts to gallons [liquid], just multiply the value in quarts by the conversion factor of 0.25. So, 7.8 quarts times 0.25 is equal to 1.95 gallons [liquid].

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
