Question

an experiment calls for you to use 100 mlml of 0.80 mm hno3hno3 solution. all you have available is a bottle of 4.2 mm hno3hno3 . how many milliliters of the 4.2 mm hno3hno3 solution do you need to prepare the desired solution? how many milliliters of water do you need to prepare the desired solution?

Answer 1

19.04 milliliters of water do you need to prepare the desired solution.

Formula, C1 × V1 = C2 × V2

C = Concentration

V = Volume

V1 = 100 ml

C1 = 0.80 M

C2 = 4.2 M

V2 = ?

Put these values in the formula, C1 × V1 = C2 × V2

V2 = (C1 × V1) / C2

     = (0.80 × 100) / 4.2

     = 19.04 ml

Therefore, 19.04 milliliters of water do you need to prepare the desired solution.

In chemistry, a homogenous combination of two or extra materials in relative quantities that may be various continuously up to what is known as the restrict of solubility. The term solution is typically carried out to the liquid country of be counted, however answers of gases and solids are possible.

So, based totally on the quantity of solute gift, answers are labeled into three sorts: unsaturated solutions and saturated answers. Unsaturated answer: an answer wherein greater amount of solute may be dissolved with out elevating its temperature, is referred to as an unsaturated solution.
