Question

lela has 1.2 liters of 2.1 molar NACl WHAT IS THE MASS OF TABLE SALT DISSOLVED?

Answer #1

molarity of NaCl = 2.1M

volume of solution = 1.2liters

no of moles of NaCl = molarity*volume in L

= 2.1*1.2 = 2.52moles

mass of NaCl = no of moles * formula weight of NaCl

= 2.52*58.5 = 147.42g >>>>answer

You
are dissolving 12g of NaCl using 210.0 g of water. After the salt
has dissolved the liquid has a final volume of 235.0mL . Molar mass
of NaCl is 58.4g/mol .
How many grams of NaCl are dissolved in 10.2mL of liquid that
has a concentration of 14.1% (m/v) NaCl?

Table salt, NaCl ( s ) , and sugar, C 12 H 22 O 11 ( s ) , are
accidentally mixed. A 3.50 g sample is burned, and 3.50 g of CO 2 (
g ) is produced. What was the mass percentage of the table salt in
the mixture? percentage of NaCl

What mass of NaCl is dissolved in 150g of water in a .050m
solution?

A tank contains 210 liters of fluid in which 20 grams of salt is
dissolved. Brine containing 1 gram of salt per liter is then pumped
into the tank at a rate of 3 L/min; the well-mixed solution is
pumped out at the same rate. Find the number A(t) of grams of salt
in the tank at time t.

A tank contains 120 liters of fluid in which 50 grams of salt is
dissolved. Brine containing 1 gram of salt per liter is then pumped
into the tank at a rate of 4 L/min; the well-mixed solution is
pumped out at the same rate. Find the number
A(t) of grams of salt in the
tank at time t.
A(t) =

Determine the molar mass of the solute. If 2.35 g of the unknown
compound were dissolved in 30.46 g of PDB ( Kfp for PDB = 7.10
C/m)
m=molality = moles solute/kg solvent Molar mass= grams of
substance/mole of substance
1. Molar mass of solute is___________
On this molar mass calculation in a freezing point depression
experiment determine the effect on molar mass, will it be higher,
lower, or not change.
2. The thermometer you were using read temperatures consistently...
