28 ml of 0.10 m hcl is added to 60 ml of 0.10 m sr(oh)2. determine the concentration of oh− in the resulting solution.

0.52 M

Explanation:

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of solution = 0.10 M

Volume of solution = 28 mL = 0.028 L

Putting values in equation 1, we get:

Molarity of solution = 0.10 M

Volume of solution = 60 mL = 0.060 L

Putting values in equation 1, we get:

According to stoichiometry :

2 moles of neutralize 1 mole of

Thus 0.0028 moles of neutralize= of

Thus (0.006-0.0014) moles = 0.046 moles of  are left in 88 ml of solution.

Concentration of will be =

Thus the concentration of in the resulting solution is 0.52 M

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
