Question

convert 36 grams of water into moles

Answer 1

Molar mass of water = 18 gm
18 gm of water = 1 mole
Therefore
36 gm of water = (1/18)× 36
===> 2 moles

Answer 2

Answer:

Convert 36 grams of water into moles.

Explanation:

Grams to moles formula: To covert grams into moles we use the formulation as;

$n=\frac{M}{m}$      .....(1)

n = number of moles

m = molecular mass

Given:

M =36 grams of water

Calculations:

As we know that $H_{2}O$ is the formula of water.

To calculate the molecular mass we split $H_{2}O$ as $H_{2}$ and O.

Therefore,

$H_{2}=2(1)\\ O=16$

$H_{2}O=H_{2}+O$

       =2 +16

       = 18 amu

Putting all the values in equation (1) we have;

$n=\frac{36}{18}$

n= 2 moles.

Conclusion:

36 grams of water is equal to 2 moles.
