How many moles are in 6.3x1054 molecules of Ca(C2H202)2?

In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.

8.08 grams

Explanation:

Given;

Mass of the steam, m = 100 g

Change in temperature of water = (95°C - 35°C) = 60°C

Change in temperature of steam = (110°C - 100°C) = 10°C

let the mass of water by 'M'

also,

We know

specific heat of water, c = 4.184 J/Kg.°C

And, specific heat of steam, C = 2.03 J/Kg.°C

Now,

Heat released = Mass × specific heat × change in temperature

thus, for the condition given in the question

M × 4.184 × 60 = 100 × 2.03 × 10

or

M = 8.08 grams
