So the molar mass of a Hydrogen molecule is 2. If you have 10 grams of Hydrogen molecules, you have 5 moles of Hydrogen molecules (10 moles of Hydrogen atoms). Avogadro's number is 6.0225x10^23. This means that one mole of a substance has that many particles.
Answer:
Molecular Mass:
1. 40g per mole
2. 19g per mole
3. 64g per mole
4. 32 g per mole
5. 17g per mole
6. 59.5g per mole
7.58.5 g per mole
8.220g per mole
9. 78g per mole
10. 200g per mole
Explanation:
Molecular Mass = Number of atom x atomic mass of an element

Answer:
I think its E. iron and iron oxide have the same properties if it's not e its d for sure
Explanation:
iron + oxygen → iron oxide. 4 Fe + 3 O2 → 2 Fe2O.
This statement is <u>TRUE.</u>
Explanation:
Due to the high heat capacity of water, it takes much more energy to have a gram of water raised by one degree compared to one gram of land. This is why during a hot day, the ground gets hotter faster than the adjacent oceans or adjacent lakes. It also takes water to lose the same amount of energy to have its temperatures drop by one degree as compared to land. During the night, therefore, this is why adjacent water bodies remain relatively warmer than land.
