Sodium chloride has a molar mass of about 58.5 g/mol. So multiply 8 moles by molar mass to get about 468 grams.
Hydrogen gas is H2. 1 moles H2 has a molar mass of 2.0158. Thus, 4 moles H2 gas has a mass of2.0158 g/mole x 4 moles = 8.063 g
For this problem, the atomic mass is not required. Take the mass in moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for the units to cancel.8.00 moles × (6.02 × 1023 atoms) = 4.82 × 1024atoms
N2 + 3H2 -----> 2NH3 so 3 moles of hydrogen produce 2 moles of ammonia. Therefore 12.0 moles of hydrogen will produce 8 moles of ammonia.
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
There are 45mg of sodium in an 8 oz serving of Sprite.
The mass is 467,52 g.

We need 8 moles potassium chloride.
0.2 mol
Sodium chloride (NaCl) contain two atoms: 1 sodium and 1 chlorine.

There are 2 atoms (1 sodium, 1 chlorine) in each formula unit of sodium chloride.
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
The crystalline structure of sodium chloride is face-centered cubic.
The solution of pure sodium chloride is neutral.
The Elements Symbol Is : Na
No it is true. 1 mole of helium is 4 g. So 2 moles will be 8 g.
