Question

find out the molar mass of X when 100g of X is dissolved in 500ml of solution if molarithbof solution is 0.5​

Answer 1

To find out the Molar mass M of solute

as we are provided with molarity , given mass of solute and volume of solution.

we know the formula of molarity i.e.=Given mass of solute / Molar mass of solute × volume of solution in litre.

Answer 2

Answer:

The correct answer for this question is $400$ gram per mole.

Explanation:

Here, we are provided with molarity, given mass of solute and volume of solution.

we know the formula of molarity i.e.=Given mass of solute / Molar mass of solute × volume of solution in liter.

The molar mass of X =?

Molarity of the given solution = $0.5$

$= 0.5 =$ mass is given of solute /molar mass a of solute $*$ volume of solution ( in liters)

= $0.5 =$ $100g * 1000/M *500 ml$

$= 0.5 = 100 M * 0.5$

$= 0.5 * 0.5 / 10000 = 1/M$

$= 1/400 = 1 / M$

$= M = 400g / mole$

Therefore, from above we can conclude that the correct answer to this  question is $400g / mole$.
