Answer:
Percentage composition H in HBr = 1.236%
Percentage composition Br in HBr = 98.764%
Explanation:
H = 1g/mol
Br = 79.904g/mol
HBr = Molar Mass 80.904 g/mol
Percentage composition of X = (X / Molar Mass) x 100
H = (1/80.904) x 100 = 1.236%
Br = (79.904/80.904) x 100 = 98.764%
Answer:
Because you have to give the simplest ratio of equation. Equation I can be simplified by dividing all the coefficients by 2 to make it into equation II.
*Every equation has to be in the simplest form of coefficients.
Ratio of Equation I :
2 : 4 : 2 : 4
Ratio of Equation II :
1 : 2 : 1 : 2
Answer: The molarity of the solution is 2.00 M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in L = 1.00 L
moles of solute =

Thus the molarity of the solution is 2.00 M
