Answer:

15.5 gm

Explanation:

What is the mass of phosphorus that contains twice the number of atoms found in 14 g of iron?

[Relative atomic mass : P = 31; Fe = 56]

14 gm Fe = 14gm/ 56 gm/mole = 14 mole gm/56gm = 14/56 mole

0.25 moles

2 X 0.25 = 0.5 moles

1 mole P = 31 gm

so

0.5 moles P =31/2 =15.5 gm

What is the molarity of a solution containing 8.0 moles of solute in 120mL of solution?
Nataliya [291]
Answer:
200/3 M which is approximately equal to 66.6667 M

Explanation:
Molarity is defined as the number of moles of solute per liter of solution.

It can be calculated as follows:
molarity =  \frac{number of moles of solute}{liters of solution}

We are given that:
number of moles of solute = 8 moles
volume of solution = 120 ml = 0.12 liters

Substitute with the givens in the above equation to get the molarity as follows:
molarity = \frac{8}{0.12} =  \frac{200}{3} = 66.6667 M

Hope this helps :)
