The amount of a
substance can be converted into grams of that substance by using the molar
mass. It is a physical property of a substance which describes the mass per
mole of the substance. The molar mass of CH3OH is 32.04 g/ mol. Multiplying the
given amount of CH3OH with the molar mass will yield to the mass of the substance.
<span>9.09x10^24 molecules CH3OH ( 1 mol / 6.022x10^23 molecules) (32.04 g/mol) = 483.63 g CH3OH
Dividing the molar mass of N2O which is 44.08 g/mol to the given amount will yield to the number of moles.
0.183 g N2O / 44.08 g/ mol =0.0042 mol N2O</span>
Answer:
1.43 grams
Explanation:
Fe = 55.8 grams Fe = 1 mole Fe
2.56 • 10^-3 moles Fe / 1 • 55.8 grams Fe / 1 mole Fe = 1.43 grams Fe
Basically, you're just multiplying the molar mass of Fe (iron) by the moles of 2.56 • 10^-3 Fe, to find how many grams are in it.
2.56 • 10^-3 moles Fe = 1.43 grams Fe

Here's what I get
Explanation:
Ethylamine has an N atom with a lone pair of electrons.
It can act as a Brønsted-Lowry base and accept a proton from water and become an ethylammonium ion.
The structure of the ion is shown below (there is a C atom at each of the four-way bond intersections).
Answer:
hi im new because of its solid state
Explanation:
Answer:
From least polar covalent to most polar covalent;
S-I< Br-Cl < N-H< Te-O
From most ionic to least ionic
Cs-F> Sr-Cl> Li- N> Al-O
Explanation:
Electro negativity refers to the ability of an atom in a bond to attract the shared electrons of the bond towards itself.
Electro negativity difference between two atoms is a key player in the nature of bond that exists between any two atoms. A large difference in electron negativity leads to an ionic bond while an intermediate difference in electro negativity leads to a polar covalent bond.
Based on electro negativity differences, the bonds in the answer have been arranged in order of increasing polar covalent nature or decreasing ionic nature.
