Molar mass of (NH4) 2SO3 is 116.1401 g/mol
Answer B I believe
Not sure if it’s correct but Lina positive it is
Answer:
0.315 atm
Explanation:
PV = nRT
P(96.2) = (1.24)(0.08206)(25 + 273)
P = 0.315 atm
CaCN2 = 35%
To calculate the mass percent of element in a given compound, we use the formula:
<h3>
What is the mass percent?</h3>
A mass percent is a technique of or expressing a concentration or a factor in a combination. A degree could be manifested using the mass percent. The mass percentage of the solute consisted in a given mass of solution can be used to describe the solution composition.
<h3>
What is solute?</h3>
A solute is a matter that is dissolved in a mixture. A solute is called a substance. While preparing a solution, there are three factors involved: the solute, the diluent and the resulting solution. A solute is dissolved in a diluent, and one or more solvents or solutes form a solution.

Answer:
C = 107.97 mol/L
Explanation:
Given data:
Volume of solution = 1.38 mL (1.38 mL× 1 L /1000 mL = 0.00138 L)
Mass of ammonium sulfite = 17.36 g
Concentration of solution =?
Solution:
We will calculate the number of moles of ammonium sulfite.
Number of moles = mass/molar mass
Number of moles = 17.36 g / 116.15 g/mol
Number of moles = 0.149 mol
Concentration:
C = n/V
C = concentration
n = number of moles of solute
v = volume in L
C = 0.149 mol / 0.00138 L
C = 107.97 mol/L
