The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units....
hope that helps
so i think that it is false because base on the statement above si the decision is yours just read it thanx
Answer:

Explanation:
Hello,
In this case, for the computation of the energy loss when the cooling process is carried out, we use the shown below equation:

Whereas we need the mass, specific heat and change in temperature of iron within the process. Thus, the only value we need is the specific heat that is 0.444 J/(g°C), therefore, we compute the heat loss:

Negative sign points out the loss due to the cooling.

75% hydrogen
25% helium
2%carbon, nitrogen
This is biology btw :P arteries carry oxygenized blood away from heart, veins carry deoxygenized blood back to heart, and capillaries are tiny networks of blood vessels that give blood(oxygen) to body tissues
