<span>7.86 g / 1 mL
divide g by 1000 for kg and divide mL by 100 for dL
</span>0.00786 kg / 0.01 dL = 0.786 kg/dL (density)
3.67 kg / 0.786 dL = 4.6692 dL
Another approach:
3.67kg > (3.67kg x 1000) = 3670 grams
3670 grams / 7.86 (density) = 466.92 mL
466.92 mL (divide by 100 for dl) = 4.6692 dL
Answer:
1.3 M
Explanation:
The question asks to calculate the molarity of a solution.
We have to use the following equitation:
Molarity = # moles / 1 lt of solution
In this case we have a solution composed of 0.65 mol of NaF diluted in a total volume of 0.5 lt. We will have to do the following cross multiplication solving for x:
0.65 mol NaF / 0.5 lt = x mol NaF/ 1 lt
x = 1.3 mol NaF / 1 lt = 1.3 M
There is 40 g of sugar in a 500 ml bottle of lemon juice
<h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight/volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
the concentration of sugar in lemon juice :
So for 500 ml juice :
