Can someone help me with this molar mass problem?[It’s the last one]
quester [9]

Answer:

54.18 \times 10^{23} \ moles in 3 mole of  Al_2(SO_4)_3

Explanation:

It is clear that in the given 1\ mole of Al_2(SO_4)_3 have 3\ ions of SO_4^2^-

Therefore 3 moles of Al_2(SO_4)_3 will have 3\times3=9 \ ions of   SO_4^2^-

Since 1 ion of anything is equivalent to 6.02\times10^{23} \ moles

Therefore 3 moles of Al_2(SO_4)_3 will have 3\times3=9 \ ions of   SO_4^2^-

Which is equivalent to 9 \times6.02\times10^{23}=54.18\times10^{23} \ moles

Thus 3 moles of  Al_2(SO_4)_3 gives 54.18\times10^{23} \ moles of  SO_4^2^-.

A solution is prepared using 0.125 glucose C6H12O6 is enough water to make 250 g of total solution the concentration of the solu
Nastasia [14]

Answer : The concentration of solution in ppm is, 500 ppm

Solution : Given,

Mass of solute (glucose) = 0.125 g

Mas of solution = 250 g

Parts per million (ppm) : It is defined as the mass of a solute present in one million (10^6) parts by the mass of the solution.

Formula used :

ppm=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6

Now put all the given values in this formula, we get

ppm=\frac{0.125g}{250g}\times 10^6=500ppm

Hence, the concentration of solution in ppm is, 500 ppm
