Relation between Mole and Mass is,

Mole = Mass / M.Mass

Putting values,

Mole = 2.3 × 10²⁴ g / 107.87 g/mol

Mole = 2.13 × 10²² moles

How many grams of water would require 2200 joules of heat to raise it’s temperature from 34 degrees Celsius to 100 degrees celsi

Arada [10]

Answer:

Mass, m = 7.97 grams

Explanation:

We have,

Initial temperature was 34 degrees Celsius

Heat produced in it is 100 calories of heat

The specific heat capacity of water is 4.18 J/g °C

The heat produced due to change in temperature is given by :

$Q=mc(T_f-T_i)$

m is mass of water in grams

$m=\dfrac{Q}{c(T_f-T_i)}\\\\m=\dfrac{2200}{4.18\times (100-34)}\\\\m=7.97\ g$

So, 7.97 grams of water is required to produce heat of 2200 joules.
