Question

The number of moles of water contained in 36 kg of water is

Answer 1

Answer:

2000

Explanation:

given mass of water 36kg=36*10^3gm

we have formula

given mass/molecular mass of compound=no. of moles

36*10^3/18

Answer 2

Concept Introduction: The stoichiometry is the basic part of chemistry.

Given:

We have been Given: Given mass of water is

$36kg = 36000g$

To Find:

We have to Find: The number of moles of water contained.

Solution:

According to the problem, The mass of a water molecule is

$(1 \times 2) + 16 = 18g$

therefore no. moles in given mass of water is,

$\frac{36000}{18} = 2000moles$

Final Answer: The no. of moles are

$2000 \: moles$
