Answer: There are 0.056 moles present in 3.45 g of .
Explanation:
Given : Mass = 3.45 g
Moles is the mass of substance divided by its molar mass.
Hence, moles of (molar mass = 61.98 g/mol) is as follows.
Thus, we can conclude that there are 0.056 moles present in 3.45 g of .
No, they both refer to the ratio of moles in compounds of a chemical reaction. Along with mole ratio and molar ratio, this can also be called the mole-to-mole ratio.
Hope this helped :)
A mole of anything contains 6.022x10^23 items. so we need to divide this
1.3 x 10^25 / 6.022 x 10^23 = 21.59 moles
Answer:
