5 0

Answer:

Q = 5036.9 calories

Explanation:

Given that,

Mass, m = 167.9 g

The temperature raises from 25°C to 55°C.

The specific heat of water,c = 4.184 J/g °C

We need to find the heat added to water. We know that,

Q=mc\Delta T\\\\=167.9 \times 4.184\times (55-25)\\\\=21074.8\ J

or

Q = 5036.9 calories

So, 5036.9 calories of heat is added.

What is the average atomic mass (in amu) of element M?
valkas [14]
An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.
