Equilibrium constants use the following set up
Keq= [products]/[reactants]
i have attached a drawing with the expression
Answer: Number of Significant Figures: 3
The Significant Figures are 6 0 2
Explanation:
6.02 x10^5
Significant figures are the digits of a number that are meaningful in terms of accuracy or precision. They include:
Any non-zero digit
Zeros between non-zero digits as in 3003 or 45.60009
Trailing zeros only when there is a decimal point as in 6750. or 274.3300
So since every 20 mins the mass will be cut in half (and that happens 3 times), you have just got to divide 1g by 2, 3 times.
after 20 mins the mass will be .5
after 40 mins the mass will be .25
Answer: After 1 hour the mass will be .125g
Answer:
The answer is HCl → H 2 O H+ + Cl.
Answer:
2.48 mol/L.
Explanation:
- The molarity of the solution can be expressed as <em>the number of moles of solute in 1.0 liter of the solution, </em>(M = n / V).
- It is also can be calculated from the relation:
<em>M = (mass / molar mass) solute x (1000 / V of solution)</em>
The solute is toluene and the solvent is benzene.
mass of toluene (solute) = 57.1 g,
molar mass of toluene (solute) = 92.14 g/mol.
volume of the solution = 250 ml.
∴ M = (mass / molar mass) solute x (1000 / V of solution) = [(57.1 g / 92.14 g/mol) x (1000 / 250 ml)] = 2.48 mol/L.
