When zn(oh)2(s) was added to 1.00 l of a basic solution, 1.09×10−2 mol of the solid dissolved. what is the concentration of oh−
uysha [10]
The concentration of the basic solution is determined by:

N = (number of moles / volume of solution) 

number of moles = 1.09 x 10^-2 mol
volume of solution = 1 liter
N of basic solution = 1.09 x 10^-2 mol / 1 liter
N = 1.09 x 10^-2 mol/L

The initial concentration of Zn (OH)2 is 0; the basic solution is 1.09x10^-2 M, then the concentration of OH in the final solution is 1.09x10^-2 M

The empirical formula of a molecule is C2H6. In an experiment, the Molar mass of the molecule was determined to be 90.21g/mol. U
Firlakuza [10]

Answer:

C₆H₁₈

Explanation:

Let's say x is the subscript of carbon and y is the subscript of hydrogen.  We know from the empirical formula that the ratio of x to y is 2 to 6.

x / y = 2 / 6

We also know from the molar mass that:

12.01x + 1.01y = 90.21

Solving the system of equations:

2y = 6x

y = 3x

12.01x + 1.01(3x) = 90.21

12.01x + 3.03x = 90.21

15.04x = 90.21

x = 6

y = 3x

y = 18

The molecular formula is therefore C₆H₁₈.

How is this SI unit of temperature related to the metric unit of Celsius?
shtirl [24]

Answer:

Celsius is currently a derived unit for temperature in the SI system, kelvin being the base unit. ... The two main reference points of the Celsius scale were the freezing point of water (or melting point of ice) being defined as 0 °C and the boiling point of water being 100 °C.

Explanation:

Hope it helps
