For 1 mole of any substance, there are 6.02214086 × 10^<span>23 particles (atoms, molecules, ions, etc. depending on the substance)
So, for 1 mole of water, there are </span>6.02214086 × 10^23 water particles, and so on
So, in 1 mole of Lithium, there are 6.02214086 × 10^23 Lithium atoms
Answer
Manual samplers are prone to effects of temperature, speed of wind and air concentrations.
Explanation
Manual samplers face several challenges that can act as drawbacks to obtaining accurate results. They are subjected to effects of sampling duration where long sampling times are needed to obtain adequate mass for detection. Manual samplers face challenges when measuring non-volatile species because particles are observed into the adsorption medium at a slower rate of diffusion.
The theory of plate tectonics tells exactly where the continents were before Pangaea divided.
I'm not a 100% sure but I feel strong about is
Oceans, they are larger than ponds hence they possess wider exposure with more number of surface molecules.
The answer is a. The arteries are red and transfer blood to the heart. Veins are blue and transfer blood away from the heart and to all of the different parts of the body. The capillaries are in-between the veins and arteries and provide blood to cells.
