<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
45.6 g Au ( 1 mol / 196.97 g ) ( </span>6.022 x 10^23 atoms / mole ) = 1.39x10^23 atoms Au
I think they are primary producers, as they produce biomass from inorganic compounds (CO2)

The concentration of a solution is basically the ratio of the solute present to the solvent in the solution. This is an intrinsic property, independent of the amount of solution that is present. A similar example is that of density. No matter the size of a sample, the density and concentration of that sample remain constant.
Answer:
From the solubility curve, which salt shows the least change in solubility as the temperature increases? NaCl
Explanation:
Answer:
8.3ml
Explanation:
to get volume u have to divide 25g over the density, i rounded to the nearest tenth, if you don't want to then write out the full number with all the decimals
